20 seconds spare? Run a speed test

Our speed tests have a tendency to get more and more complex as everyone asks for various features to be added, but we thought lets do a stripped back version for once.

Our regular visitors will be well aware of our monthly speed test summary which provides regular and timely updates on what people are actually experiencing rather than what the PR machines of the providers want us to believe. All the speed tests with a postcode feed into our coverage site where the postcode level analysis updates monthly and also features a more complex speed tester that lets you browse other peoples tests once completed.

Hi Andrew Staff
A much better speed test just run three on Gu266qd and it is showing on my upgrade from 40/10 to 50/10 that the average is increasing could this be due to the DLM kicking in time will tell.

2 out of 3 times our ADSL line times out on a speed test (any speed test).

Does this get recorded as 0 and added into the mix?

  • Llety

If the test makes it to the results page it has been recorded by us as a valid test. We do record failures but impossible to know reasons for failure so are not added to the overall statistics.

http://tbb.st/1463659182261555655 a recent slow test, and people many slower and have seem some that say 0 down and up to 1 decimal place, i.e. are below 0.05 Mbps dial-up speeds

Are there any plans to stop using port 80 so my web filter and antivirus can't interfere with the results?

  • tombartlett

https://labs.thinkbroadband.com/speedtest Page and testing is over SSL so port 443

I agree you can't know the reason for failure, but if a download starts and does not finish, the most likely explanation is network failure and so should be considered when counting the average for the post code or at least sample size and number of failures reported.

Of course the submitter could have got bored, laptop run out of power, etc, etc.

Not factoring in failed speed tests as 0 skews the numbers away from the real experience.

Here is a speedtest on Three 4G on 1 bar in the HA8 area (north West London)

The problem is we do not know if the user would have recorded 0.00001 Mbps, 0.1 Mbps or 10 Mbps or 100 Mbps so what do you record?

  • andrew

Are you going to ditch the flash speed test at some stage?

  • Apilar
  • about 1 year ago

Record that attempt as zero. If you have 2 samples, 1 worked at 10mb, the other failed after the session started, then the mean is 5mb.

I believe it is the right thing to do from a statistical perspective, unless you also show the
number of success and failures.

  • Llety

@ Apilar: I hope they don't Because for me the flash tester gives more reliable results, the HTML5 tester seems to be too fussy about which browser is being used and AV security suite in use, On my Win 7 x64 box there's a bug on both speed testers where the single thread test will max at around 28-30mbps opera and HTML5 is quite persistent but randomly does this with the flash based tester, Firefox displays issues too

  • tommy45

@Llety they shouldn't be recorded at all as a failed test has no bearing on the line speed as it could have been the browser crashing or similar. Someone looking to understand line speeds does not want duff tests that have possibly got nothing to do with the connection itself.

  • ian72
  • about 1 year ago

Sorry, when I say not recorded I mean not included in the mean. Recording them is fine as long as it doesn't skew the stats for unknown reasons.

  • ian72
  • about 1 year ago

@llety
It might be valid to hold 5Mb as *your* average. It gives an accurate depiction of your experience.

However, reporting that as an accurate indication of what the local area can expect is simply bogus.

Why on earth would I want to see a figure that incorporates results of one person's incompetence at maintaining their PC/network/wiring/device?

  • WWWombat
  • about 1 year ago

Hmmm. Recently, the standard "flash" test has taken to going askew, especially upstream - which it measures as 10Mbps. Downstream isn't immune either.
http://www.thinkbroadband.com/speedtest/results.html?id=146367347525378714428

This "quick" test seems more accurate, with an 18Mbps upstream...

@llety followup
Thinking about it further...

If you really wanted to keep some idea of tests that failed in an area, it would be far better to track the rate of success/failure separately from the actual speed average.

eg 25Mbps average, 99.3% tests completed.

  • WWWombat

This 20second test has issues with Opera running on WIN 7x64 it gives a ridiculously low upload result for me less than 2mbps ( average: 0.93 and 1.05 burst) yet firefox on the same box gives a more realistic result on the upstream of 18.2mbps and 19.2 burst,The downstream results with firefox where more accurate, as was the latency of 26ms, as opposed to the opera result of 170ms

  • tommy45
  • about 1 year ago

@tommy45 So this is different behaviour to http://labs.thinkbroadband.com/speedtest and https://labs.thinkbroadband.com/speedtest is that what you are saying?

  • andrew
  • thinkbroadband staff
  • about 1 year ago

From the testing i have done so far it's mainly the upstream being lower with this 20sec test, although the last i did with firefox on the xp box showed an improvement though still a bit low

above link is the result from win 7 box running opera
http://www.thinkbroadband.com/speedtest/button/1463695678278137855.png is same pc but with firefox

I just fan the main HTML5 test again same box os and using opera http://www.thinkbroadband.com/speedtest/button/1463696254452459355.png

same/similar low upstream results as the short test

  • tommy45
  • about 1 year ago

So not new test version breaking it, but something Opera is up to that needs to have a work around found.

Opera does seem to have a history of breaking uploads of material from browsers though

My upstream issue was with a chrome browser on Win7.

  • WWWombat
  • about 1 year ago

I note the test says "Please note that this test will not link to your profile.", which is the same as running from the Big Orange Button link (actually why I visited today). Are there plans to fix this? I've found that having a historical graph of results to be really useful, especially to confirm a couple of line-faults I've had.

Why does the Share button take one to Faeces Book

  • drwright
  • about 1 year ago

The f share button has the usual facebook share icon on it, there is also a twitter and a standard URL button.

  • andrew
  • thinkbroadband staff
  • about 1 year ago

@danielmec The tester is all ready to link to the profiles it just needs some stuff done by others as part of a wider set of changes to happen.

  • andrew

@andrew Thanks! As always its great to see tbb making usability improvements.

Okay the Opera issue is down to its turbo mode, turn it off and all is fine.

  • andrew
  • thinkbroadband staff
  • about 1 year ago

I notice that your speedtests are multithreaded, this means that by load balancing I use both lines and achieve about 85mbit.

I do wonder if some poor soul coming to the area later will think that they can get that, only to discover a single FTTC line is about 45mbit...

  • rtho782
  • about 1 year ago

Opera users now have a warning message - have tried to detect turbo mode but it seems Opera changes its mind sometimes, so you can be part way through a test and flips, so not reliable enough as a warning before hand.

  • andrew
  • thinkbroadband staff
  • about 1 year ago

On load balancers - rare enough to not be a major issue

  • andrew
  • thinkbroadband staff
  • about 1 year ago

This speediest is nonsense. I average 71Mb/s on various speed test services. This one shows 14Mb/s.

  • danieltemple
  • about 1 year ago

@danieltemple Sorry to hear that, can you visit http://labs.thinkbroadband.com/speedtest and run that test and post a copy of the share results link at the end so we can look at why this may be.

  • andrew
  • thinkbroadband staff
  • about 1 year ago

why is this threaded only? lets poor performing providers slip through.

  • chrysalis

Is this one still based on flash?

  • rndmartin
  • about 1 year ago

No - no flash in this or the version at http://labs.thinkbroadband.com/speedtest or on https://labs.thinkbroadband.com/local (in the search tab)

  • andrew
  • thinkbroadband staff
  • about 1 year ago

How accurate is this version of the test? I only ask as I log into my account and get 73Mbps Down and approx 11 Mbps up on the speed test. My wife can switch profiles, go to your site, runs a test without logging into an account and gets 75Mbps Down and 18.5Mbps up on the speed test. Same machine only 30 seconds difference between tests. Any ideas?

  • hairybarsteward
  • about 1 year ago

@hairybarsteward Believe overall the new test (that has been running for 3 years, this is just a different skin) is the best and this gave you http://tbb.st/1463749053782821855 72Mbps down 18Mbps up

The older flash based test gave a slower upload http://tbb.st/146288941967770526637 and this is why its slowly being phased out.
