Title: Is bt speedtester totally broken?
Post by: SSK on Sep 16, 2010, 12:02:58

Over the last couple of days while my ADSL2+ has been settling in I've been getting crazy results from the bt speedtester (see below). Is this just me? If so, what might be the problem.

e.g.  Last night it told me:
Download speed - 8251 Kbps
DSL Connection Rate - 3456 Kbps
IP Profile - 5000 Kbps
Upload speed - 714 Kbps
Upstream IP profile - 448 Kbps

Can download speed really be about twice the connection speed??

less than a minute later my router was telling me:
Up speed - 12755000
Down speed - 1106000
SNR (down) - 14
Loop Att - 29

Today, a few mins ago it gave me:
Download speed - 9998 Kbps
DSL Connection Rate - no number given
IP Profile - 38717 Kbps
Upload speed - 629 Kbps
Upstream IP profile - 10000 Kbps

The router is still giving the same stats as above except SNR is now 15.

Of course, bearing in mind the almost incoherently abysmal standard of English on the site, the lack of functionality isn't too surprising.
(although I was amused by "represent the ratio while sententiously passing...").

It's a bit bent out of shape, Sean - it reported that I was downloading faster than my profile, and that my sync speed was 1.5M lower than my actual sync speed last time I used it. I generally ignore it unless there seems to be a line problem, when it's the only test that counts.

I've just run a test and the results look completely normal (and correct). It seems its not completely broken for everyone!
Title: Re: Is bt speedtester totally broken?
Post by: Ray on Sep 16, 2010, 12:13:15
Works OK for me as well.

Download speedachieved during the test was - 5153 Kbps
For your connection, the acceptable range of speeds is 1200-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8128 Kbps(DOWN-STREAM), 832 Kbps(UP-STREAM)
IP Profile for your line is - 7150 Kbps

Yes,  it's the only test that bt will accept if there is a line problem, so it's rather sad that the results it gives can be pretty meaningless.

As a follow-on question...
Sometimes (as on the two occasions above) it gives me the choice of going on to a third test which requires changing the login settings on the router. However, I've not gone on to do that as I'm concerned it will cause a disconnect and might mess up the the 10 day "training period" of my ADSL2+ connection. Is my concern valid?

Thanks,

Sean

It is, imo. It usually only offers that test if there's an error count on the line. The only time I've seen it was this week with the Stepney Green outage, which was causing massive packet loss across the country.

No-one has ever given me a definitive answer on whether there is one BT tester, or several sites which you may be routed to for geographical or network reasons. I suspect the latter because, in the past, I've had a perfect result when others have been seeing anomalies. :dunno:

Is that constant, Mitch. I suppose the other possibility is that there's a bunch of servers and they're not all running the same version of the tester.  :dunno:

theres some thing wrong with it isnt there.I just tried and D/L showed as less than half what I normally get and U/L was the same.actual speed was slightly down.Router is showing as normal and I also got the option for a third test.


Try any other speed tester and I get the normal results for me

[oops! - I think I probably put this in the wrong forum and it should be in Brodband New & Discussion - sorry, slip of the mouse!]

Anyway, just done another bt test....
Download speed - 9973 Kbps
DSL Connection Rate - 12752 Kbps
IP Profile - 2500 Kbps
Upload speed - 697 Kbps
Upstream IP profile - 1104 Kbps

Apart from the IP Profile, it's not quite so silly now. (I think IP profile is a random number generator!)
Router says I'm connected at 12755 Kbps, with SNR = 15 and Att 29, Pretty much as it has been for the last 36 hours.

Don't get me going about BT - with my previous ISP I was off line completely for 17 days and 22 hours because for 10 days BT wouldn't accept there was a fault at the exchange. Even then it took a couple more days to send an engineer to the exchange. When he found the card was faulty it took them some more days to fix because (they said) they had no spare cards in stock.

You have now. ;)

I know how you feel about BT, I was offline for 10 days because they swore I was in sync when I didn't even have a router connected to the line. Turned out to be a faulty line card.  :mad:

Post by: SSK on Sep 17, 2010, 21:31:46

People sometimes complain that their IP profile doesn't change quickly enough to match increased connection rate. Well, in the past 24 hours the bt tester has given me the following values:
download speed     connection rate    IP Profile
11452                   576                    11000
9999                    12444                 13000
10884                  12444                 10000
9434                    12444                  3000

From these stats and those in my first post in this thread (for the 24 hours before that), the IP profile seems to be changing in both directions pretty quickly. I thought it wasn't possible to get download speeds greater than connection rates or download speeds three times the IP profile?

The router has been rock solid for about 3 days with connection rates between 12444 and 12755,  SNR around 15, and Loop Att between 29 and 31. The only disconnects (according to my router) have been at around 6.30am , which I was told was the BT equipment doing a re-synch.

Now obviously the speeds are good (though I'm sure I could get better if the SNR hadn't been stuck at 15) but I'm a bit concerned that the occasional silly values for IP profile and connection rate might indicate a fault with the card in the exchange and maybe that fault, rather than any real noise, made my SNR jump from 7 to 27 overnight just a few hours after being upgraded to ADSL2+

The 10 day 'training period' will be over on Sunday morning. Will it then be okay to temporarlily disconnect while I upgrade my router firmware? If the SNR is still stuck on 15 at that time, will that be its default position unless I can get it changed manually?

Hi Sean

The BT tester does sometimes appear to be a work of fantasy rather than a useful tool, but rapid changes in profile should follow a major change in sync rate.

You'll be safe to upgrade the firmware tomorrow. Target noise margin will only reset if IDNet can do it manually, or you wait 14 days with a constant, error-free connection, when it will drop by 3db, repeating every 14 days until you reach 6db or the line becomes unstable.

It's a pity, because if BT were to put a bit of effort into it, it could easily be a very useful diagnostic tool.

First job of course would be to give it to a proper programmer instead of a 16 year old kiddie on work experience, but as it's the easiest way to find out your IP profile it shouldn't be too much problem to provide other information as well. Target SNR, whether you're on a banded profile (and why), maybe a bit of connection history and some sort of comment about line quality (eg what sort of percentage the error rate is of the value where the DLM will take action).

Could save a lot of BT's time if those figures were available, and sites like this and tbb (not to mention the ISP) had a useful basis to help users with problems.

I can understand they don't want their servers taken up with speed tests, so if they got it working properly I wouldn't even mind if they increased the current one hour between tests to two hours!
Title: Re: Is bt speedtester totally broken?
Post by: Rik on Sep 18, 2010, 12:02:59
I agree, Bill, but BT seem to want to veil the whole process in secrecy. Possibly, they fear that making the data available to people who don't understand it will only increase problems for ISPs?
Title: Re: Is bt speedtester totally broken?
Post by: Bill on Sep 18, 2010, 12:49:18
I thought of that as a possibility, but I think firm evidence that BT care much about ISPs' problems anyway is a bit lacking :P

The extra info could be hidden behind a "Use only on ISP instructions" checkbox on the login page...

I just got this

Download speedachieved during the test was - 6560 Kbps
For your connection, the acceptable range of speedsis 1000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8118 Kbps(DOWN-STREAM), 888 Kbps(UP-STREAM)
IP Profile for your line is - 7000 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 11.08:23.53:65.38 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

The results of this test will vary depending on the way your ISP has decided to use these traffic classes.

2. Upstream Test: -provides background information.

   Upload Speed
   0 Kbps
   
0 Kbps   888 Kbps

so no upload speed  :)       never used to get an upload speed test before  :dunno:

Not sure whether IDNET provide the info but I have a line data option on the customer portal panel which shows the last 10 resync events and when the Run Mode (fastpath/interleaved) changes either as a result of manual or automatic change but does depend on BT feeding the info directly into it.

This kind of info Bill mentions would be useful in a portal for tech savvy users.

My BT speedtest never gets past the Checking User details screen... it just sits there forever.. I only know its been a problem for the last week and have checked for the obvious (eg. firewalls), and the same occurs on another pc on my lan too.  Have also tried Opera, Firefox and IE, same issue on all.

Anyone else getting this issue?

Post by: Rik on Sep 20, 2010, 10:05:43
Same here, but many people see what you do, Gyruss. I can only put it down to time of day or, perhaps, AV software in use. You are running the latest Java I take it?
Title: Re: Is bt speedtester totally broken?
Post by: gyruss on Sep 20, 2010, 10:16:16
Yes, latest JAVA, and checked to ensure no firewall hits from the IP shown in the bt speed test too.  It sits there awaiting response from the IP shown in the bottom left hand corner.

When the 'upgrades' were done the other sunday and everyone had problems with DNS etc, and there was talk of routing tables with issues, i've not been able to do a speedtest since then.. so i'm wondering if the upgrade(s) are part of the problem? (yes i know its pure coincidence, but nevertheless its worth mentioning)

In another post i've made too, i'm not able to download the latest world of warcraft patch using the blizzard updater too, its just sat there doing absolutely nothing, which is wierd, it usually does something at least.   
Title: Re: Is bt speedtester totally broken?

I don't think the upgrades can be part of the problem, as they would affect everyone. Try running traces to both sites and see what you get.

It's been over a week now since I started getting impossible results (first post in thread) from the bt speedtester.  And still most tests I do come up with impossible results - e.g. last night it claimed that my download speed (11793 Kbps) was much bigger than my connection rate (2268 Kbps) while my IP profile was (allegedly!) 10000 Kbps.

Again this morning it told me that my download speed (10052 Kbps) is even much more biggerer than my connection rate (576 Kbps) while my IP profile is still (allegedly!) 10000 Kbps. On both occasions my router stats have been the same - it says it's connected at 13624 Kbps, SNR 14 and Loop Att 23.

ISTM that either the bt tester is still broken and useless or that the card in my exchange is faulty and sending false information to BT.

If the tester has been broken for so long, I wonder if BT even know about it?

Is there any contact email address for the bt test site so I can complain? Or shall I contact IDNet support and ask them to complain to BT about it?

I'd suggest going through IDNet, Sean, they may be able to see some reason for what;s happening and, if not, they are better placed to get a response from BT for you. It is a curate's egg at them moment, though, it works or it doesn't, it gives sensible results or it doesn't. It has the feel of something coded by a bored financial controller one Friday afternoon as a first exercise in programming. ;)

Thanks Rik,

I've sent an email to IDnet support. Hopefully they can find out from bt what's going on.
In the past 24 hours 4 out of 4 tests have come up with impossible numbers.

BT may have hired useless code writers, but they they might at least have had the pages checked by someone who speaks English. There are so many errors, but one is funnier than all the others:
"represent the ratio while sententiously passing..."
Definition of sententious:- given to moralising in a pompous or affected manner.

Mmmm maybe they meant "sequentially passing"??
Or are BT really moralising in a pompous or affected manner?   :)

Just had a reply from IDNet support:
QUOTE
BT were carrying out work on the BT
speedtester however the changes they have implemented are working fine
for customers using the test tool at the moment. The relevant part of
your test is the throughput rate of which is reporting correctly.
UNQUOTE

I sent figures with my email to IDNet support, showing that the tester was still not working properly as recently as about 1.5 hours ago. Despite those numbers, they think it's still working fine as long as throughput is reorted correctly, even though connection rate figures are meaningless. If it doesn't matter that the connection rate and profile figures are useless, why bother having them as part of the test report?

So far I've been with IDNet for only 10 days and after 4 emails to them (one of which never received any response at all) I'm already disappointed with the standard of support. Thank heavens it's only a 1 month contract!

I think there's been a breakdown in communication. What IDNet were trying to tell you was that the important figure in your test results was the throughput. That bit of the tester is working fine. The other aspects of the tester have been reported to BT, and IDNet will keep an eye on them till they're fixed. The email to which they did not respond was one reporting speed during a period when they had asked you to monitor your speeds for 72 hours, so it was just added to the 'evidence' pile that was collected during that time as they could make no useful reply until they had all the data. The major problem with your connection is the noise margin, and whilst they have had the banding removed from your profile, they can't do anything to reset the margin, the system will decide when and if it's ready to reduce it.

Thanks for your input and for helping to sort out the communication breakdown.

IDNet no doubt have a means of knowing that the throughput part of the test result is indeed correct, but I don't. When I do a test and find some of the results are wrong, how do *I* know that the throughput part of the test is accurate? If I know that I can't trust some results (connection rate), how can I trust the others (throughput)?

I realise the problem with the tester isn't the fault of IDNet, but as long as the consumer (eg me) can't have any way of knowing what part of the test can be trusted, it seems disingenuous to claim it is 'fine'.

I run my own business and always acknowledge receipt of an email from one of my customers even if I can't do anything to action it at the time. If I don't respond how do they know if I've received it? How long does it take to write something like:  "Thank you for your email. Unfortunately we cannot do anything until at least 72 hours of data have been collected."? It just seems like basic customer relations to me.

As I'd sent an email asking for the banding to be removed, how long would it have taken for someone to send a short email to tell me when it had actually been removed? Again, to me it would seem to be basic customer relations - a little time and consideration makes a huge difference to the customer's perception of the company.

BTW - Some posts on uk.telecom.broadband have indicated that even when noise problems have been fixed it can take months (if at all) for the automated system to bring down the SNR and that ISPs can ask BT to reset it. Are those post incorrect?

Asuming no noise problems on my line, could you guesstimate how long it might take for the automated system to return the SNR to what it was before whatever mysterious 'event' triggered the banding?

I've had an excellent stable ADSL line for several years (6-7 dB SNR and loop att around 25-29 dB) and for the first 12 hours or so on ADSL2+ I had:-
Up Speed   1152000
Down Speed   18325000
SNR Margin   6
Loop Att.   27

So it's rather surprising and very disappointing to find that that suddenly overnight my line became so bad that it had to have first a banded profile and now an indefinite time on a much higher SNR.

Thanks again,

Sean
PS
After writing the above I just had an email from support saying thatbthey have asked BT to restart the training period so that within that period the SNR will be reset to 6 dB.
Thank youu to IDNet support!

IDNet no doubt have a means of knowing that the throughput part of the test result is indeed correct, but I don't. When I do a test and find some of the results are wrong, how do *I* know that the throughput part of the test is accurate? If I know that I can't trust some results (connection rate), how can I trust the others (throughput)?

You don't, tbh, all you can then do is check against other results and see if there's a significant variation. The best method is to download a largeish file from a 'known good' server.

QuoteI realise the problem with the tester isn't the fault of IDNet, but as long as the consumer (eg me) can't have any way of knowing what part of the test can be trusted, it seems disingenuous to claim it is 'fine'.

They're only saying your throughput is OK from the test, they've already escalated the rest of the speedtester issues to BT.

QuoteIt just seems like basic customer relations to me.

I'm not really in a position to comment, but I was left with the impression you knew that they needed the 72 hours to pass, so the email was just added to your ticket without reply.

QuoteAs I'd sent an email asking for the banding to be removed, how long would it have taken for someone to send a short email to tell me when it had actually been removed? Again, to me it would seem to be basic customer relations - a little time and consideration makes a huge difference to the customer's perception of the company.

Unbanding is handled by BT and you will generally know before IDNet do when it's been done.

QuoteBTW - Some posts on uk.telecom.broadband have indicated that even when noise problems have been fixed it can take months (if at all) for the automated system to bring down the SNR and that ISPs can ask BT to reset it. Are those post incorrect?

As I understand it, Max connections can be reset but WBC/21CN cannot, the DLM is different (and more sensitive). That will be changing, as it did for Max, and ISPs will be able to reset parameters themselves.

QuoteAsuming no noise problems on my line, could you guesstimate how long it might take for the automated system to return the SNR to what it was before whatever mysterious 'event' triggered the banding?

About six weeks, if the line maintains sync and has no errors. Or they can be sneaky. ;)

QuoteSo it's rather surprising and very disappointing to find that that suddenly overnight my line became so bad that it had to have first a banded profile and now an indefinite time on a much higher SNR.

I quite understand your frustration, having been on the end of this situation myself. Unfortunately, BT are judge, jury and executioner and Ofcom shows no interest in making them improve their systems. :(

Thanks, Rik, for taking the time to explain things.

Apologies if I came across as being rather strident. I just felt frustrated and powerless with the situation apparently just being left in the hands of an uncaring BT.

Certainly there seems to have been misunderstandings between support and myself, perhaps partly because they thought I knew more than I actually did about how the system works. I'm a bit shocked (but not surprised) that BT (in their arrogance) don't tell the ISP when they have unbanded a profile.

Anyway, support managed to get BT to restart the 10 day training period about 14 hours ago and the resulting resync immediately gave these router stats
Down speed  19544332
SNR  5
Loop Att 23

The latest stats this morning show
Down speed  19544332
SNR  6
Loop Att 23

So unlike the first night after the upgrade to ADSL2+, it has remained stable and hopefully (fingers crossed, touch wood, etc) it will continue to do so.

As expected, the BT speedtester still gives some silly numbers for connection rate...
Download speed - 17681 Kbps
Connection rate - 2387 Kbps

Anyone want to place bets on how long it will take BT to fix the tester?  :)

Thanks again,

Sean

I'm very happy with the situation as regards my connection now, but regarding bt tester, at the moment it looks like it can't even get the speed right... it seems to be considerably underestimating it.  So now I can't rely on the bt tester even for basic throughput speeds.

bt tester says 10791 Kbps
namesco says 15422 Kbps
speedtest.net says 1599 Kbps

bt tester also says the connection rate is 8125 Kbps

Regarding testing large files from a reliable server - can anyone recommend such a server?

Thanks,

Sean
Title: Re: Is bt speedtester totally broken?
Post by: Baz on Sep 21, 2010, 15:46:41
so its the throughput rate that is correct eh?

Download speed achieved during the test was - 3611 Kbps
For your connection, the acceptable range of speeds is 100-500 Kbps.
Additional Information:
Your DSL Connection Rate :572 Kbps(DOWN-STREAM), 444 Kbps(UP-STREAM)
IP Profile for your line is - 500 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 5.42:32.6:61.98 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

The results of this test will vary depending on the way your ISP has decided to use these traffic classes.

2. Upstream Test: -provides background information.

   Upload Speed
   0 Kbps
   
0 Kbps   444 Kbps
Max Achievable Speed

Sorry if I seem to be going on about this, but it occurs to me...
AIUI the IP profile is determined by the connection rate. So if the BT tester gives the wrong connection rate, doesn't that mean people could end up with a totally inappropriate IP profile?

For example, if my router says I'm syncing at 19544 Kbps the bt tester says connection rate is 3695 Kbps, (tonight's actual numbers) will the system put me onto a much too low IP profile?

Or does the connection rate reported by the bt speedtester not have anything to do with the rate that the system uses to calculate IP profile?

Depends on your definition of 'working'.  :)
In the past 24 hours I've done 3 tests. Presuming that throughput can't really be 3 times the IP profile (can it??), only one of tghe tests gave sensible numbers.

The last one (a few mins ago) gave this:
1. Best Effort Test:  -provides background information.
Download Speed
15575 Kbps
0 Kbps   7150 Kbps
Max Achievable Speed
Download speed achieved during the test was - 15575 Kbps
For your connection, the acceptable range of speedsis 1000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :17648 Kbps(DOWN-STREAM), 1160 Kbps(UP-STREAM)
IP Profile for your line is - 3000 Kbps

So throughput is 3 times the IP profile and is twice the Max achievable speed.  :P

'the acceptable range of speedsis 1000-7150 Kbps'
As my speed is not within this acceptabke range, should I complain?   ;D

Acceptable range of speeds - 100 - 250 Kbps

Even the download speed wasn't correct as 3 other speedtesters gave values about twice that of the bt tester (ie they gave between 14000 and 15000 Kbps).

I'd recommend believing the results from the BT speedtester (for speed anyway, the rest is open to doubt).

Basically it just downloads a known number of bytes and divides that by how long it took. Most other speedtesters process the results and can give artificially high answers, particularly if there's any congestion.

Of course that presumes that it is currently doing even that simple measurement & calculation accurately if it is broken and doesn't even know the real IP profile.

As other results of the bt-speedtester  (in this test and others over the past few days) are clearly wrong I don't see why any more belief should be placed in the download speeds it provides than in the other results it gives.

Do the BBmax, speedtest.net and tbb speedtesters all usually overestimate by a factor of two? Also, I downloaded a 200Mb file from tbb and calculated the speed to be about 1.7 times the bt tester result.

I wouldn't necessarily believe the the other testers are particularly accurate, but while the bt tester is obviously broken in other ways I certainly have no reason to believe that bt tester download speed results are any more accurate.

Earlier today the BT speedtester gave me a result of 33846Kbps down, 7060Kbps up. Those figures are in agreement with the Mac's network monitor.

The tbb speedtester gave me about 60% of that, also in agreement with the network monitor. (The tbb test works the same as the BT one but is single-threaded, and I suspect there may be peering problems with it.)

The BBMax and speedstest.net testers gave results about 3-4 Mbps higher than the network monitor would indicate. They're both Ookla-based, see here (http://wiki.ookla.com/test_flow) for a possible explanation.

All the speedtesters use different routes of course, there was some congestion visible on the monitor for all but the BT tester.

Clearly the BT tester is broken.

They give about the same result as the tbb speedtester for me.

There's something odd about it, but whether it's routing, peering or whatever I have no idea.

The only bit of "information" I have is that when there's some sort of "event" on the internet (IDNet playing with routers, BT doing major work or the like) I can get speeds of about 35Mbps from it for a few days, then it goes back to about 25Mbps :dunno:

Tell me about it :(

It's only happened since I went on to FTTC. Previously both tbb and BT would give me a nice clean flat-topped graph on the network monitor, now the tbb one looks like it's heavily congested even at times when I know it won't be.

I can't help wondering if there's something different about the way the backhaul is "fed in" to the main network from a fibre connection, but I also can't help but know that I'm out of my depth ;D

Probably poor Java coding.

perhaps IE8 64-bit may have worked, but it seems to be constantly prompting me to re-install java for the speedtester, despite the java.com demo working fine to prove functionality present within the browser.. grrr.

IE8 32-bit i guess must be the base browser they want on a windozeZZzzz pc :)

One of these days i'm going to build a Linux machine from one of my older pc's and see how that goes.

I have a vague recollection of someone (on tbb?) saying that Java for 64-bit apps isn't checked on Java.com and needs to be installed manually, so maybe IE8/64 is right.

But I can't find the post and my memory may well be at fault, so a look around the Java site may be in order.

I don't think so Rik, it only ever occurs when other tests indicate very low throughput on the downstream. When throughput is high it always seem to return a result. It's probably coincidence but it's an annoying one as it means I can't provide an 'official' log of things.

Post by: SSK on Dec 10, 2010, 11:01:33

Well, several weeks on from my initial post, the BT tester seems to have settled down, but for me the throughput  speeds reported would still appear to be unreliable.

For the past 5-6 weeks my connection rate has been17,784 Kbps with an IP profile 15,000 Kbps.

During that time I've done just over 30 bt speedtests and (with one exception) all have given throughput rates of well over 15,000 Kbps and many have been over 16,000 Kbps. For example, yesterday the bt test reported throughput as 17,010 Kbps and today it reported 15,891 Kbps.

Presuming real throughput can't be greater than the IP profile, one can only assume that the bt tester throughput speed is not reliable.

Over the same period, I've done several speed tests on both namesco & speedtest.net, and all have consistently given throughput speeds of just over 14,300 Kbps.

Despite what others might say about the bt test being more accurate, from my own results it would appear that the other speedtesters give more reliable (and more believable) results.

If it bypasses the things that normally restrict speed it's not particularly useful as a real speedtester, though I suppose it may possibly be useful as a diagnostic test for BT.  So the conclusion is that if one wants to measure one's real-world download speed don't use the BT tester.

Unfortunately, however, BT appear to use it more as an excuse to say nothing is wrong rather than as a tool to diagnose what might be wrong. For example:
Customer to ISP - My downloads from lots of different sites have recently become very slow.
ISP to customer - Have you tried the BT speedtester?
Customer to ISP - Yes, and the speeds seem okay with that.
ISP to customer - Well, that proves your problem is nothing to do with BT.
Customer to ISP - But what if the slow download problem is caused by the parts of the BT equipment or protocols that are bypassed by the BT speedtest?
ISP to customer - ?????

To be fair to BT (ouch, that hurt) it always has been intended as a diagnostic tool not a "my line is faster than yours" speed tester. That's why you can't use it more often than hourly (it used to be three hourly), and I suppose it makes some sense to bypass as many extraneous (to BT) potential bottlenecks as possible.

After all, if the BT bit shows up as OK but tests via the ISP are slow, it's not unreasonable for them to say "Not our problem sunshine", annoying though it might be.
Title: Re: Is bt speedtester totally broken?
Post by: armadillo on Dec 11, 2010, 00:57:01
No doubt someone will be able to explain why my following conclusion is wrong. But....

It seems to me that when you use the BT speedtester (by putting speedtester.bt.com into a browser), you are still connected through your own ISP and so are not bypassing anything except perhaps the limit imposed by the profile. You still go through your usual ISP's routers and lines. And I bet the downloads count towards your usage allowance. Sure, you are downloading from a dedicated BT server but the only part of the system unique to BT is that server and the connection between it and your ISP's network. I am not clear what it shows except what throughput is achieved via your own ISP from a known server for which BT are responsible.

When we did our BT speed tests by disconnecting from the ISP and logging onto the net via bt_test@startup_domain, that really was bypassing all the ISP's equipment and logging straight into a bt setup.

Please tell me why this is wrong, if it is.

FWIW, I almost always get a lower throughput from speedtester.bt.com than I do from normal real-world downloads unless I use speedtester in the middle of the night.

BT Speedtest seems to obey the profile on it's system for your line and to limit throughput accordingly.

For four days this week my BT Speedtest profile was stuck at 2.5 and my BTspeedtest download result was 2334, even though BT's BRAS systems insisted my line was already set at 3.5 

Yesterday the fault was escalated within BT and the speedtest systems had the proper 3.5 profile forced onto that system. After that the the Speedtester showed the 3.5 profile and the download was at 3486.  My Sync/SNR remain exactly the same.

I am not sure there is anyone, anywhere that understands exactly how BT's line management system works.

I'll have a look at my own config when I get in from work later.

Another little tip I've learned is that if you have multiple versions of Java installed it can screw things up like the speedtester because browser does not know which version it should use and I don't think BT specify in the code.

This leaves two options:

Uninstall all versions except the latest

or

Go into the Java Control Panel (Switch Control Panel to Classic View on XP or select additional options on Vista/7 I think)

Click the Java tab and then click View next to Application runtime settings and untick all boxes under Enabled except for 1.6.0_25

Click OK and OK on Java Control Panel.
Close Control Panel and try the test again after closing and reopening your browser.

Same result I'm afraid

The Performance Tester is currently unable to run a speed test for your broadband connection. Please try again shortly, however if this problem persists, raise the issue with your service provider.
