TBB speed testing?

When I use the new TBB speed tester the download readings are fine.
But the upload readings are a lot lower than the 17.5 Mbps that I have been getting , up to about a week ago it has only been showing about 6-10 Mbps.?
All other testers including the BTW one are ok.?
I have tried changing the DNS servers involved but it remains the same.?
BTW the upload is showing as "A" on the buffer bloat.

Have dug out your recent tests as they are revealing and show things you may have missed...

Notice how the upload speeds are good for 3 to 4 seconds then drop, as they drop before the upload is 50% done, you end up with the low reading since its reporting a median. With other testers they are likely to report a figure much closer to the burst figure, i.e. all would look good.

The upload graph suggests the connection is able to deliver, but something somewhere is halving your speed after a few seconds.

Interesting , and thanks for the info.
I will go back in time on my PC because it might be a resident background program that is using some upload bandwidth.?
But can`t think of anything at this time.

Further to my last reply ,I have done 2 more tests and now the download is dropping and is very unstable.
Might be that my line is failing ,hope not.

What router are you using....any QOS settings applied

I am using the original BT/OR router , and no QOS settings are applied.
Everything has been ok up until now and it is only the TBB tester that is picking up problems.
But as it is not making any difference online or resolving pages then it will probably not be a real pain.

I am seeing the same sort problem but it seems to be browser related We have been away for a couple of weeks. Before we went Firefox was reporting upload speeds of about 16Mbps. Got back yesterday, updated Firefox to v55.0b4 (64 bit) and it is now reporting upload speeds of 2Mbps. BTW test currently reporting 15Mbps upload.

For comparison I ran the tests on another couple of browsers.

Flashpeak Slimjet (v14.0.16.0 (based on Chromium 57.0.2987.98 (64-bit)) reports TBB 9.8Mbps, BTW 15Mbps.

MS Edge reports TBB 16.6Mbps, BTW 14Mbps.

Given the consistency of the BTW results, it looks at first glance that the results generated from the latest version of the TBB speedtest are not consistent between one browser and another. Assuming that the speedtest is working as designed it would be helpful if there was a health warning that some browsers return inconsistent results.

The health warning should be given by browsers when they offer upgrades really...

Payload upload logic is the same on upload for all browsers currently and has stood the test of time, so suggests maybe browsers have changed.

Looking through tests
http://tbb.st/1498668673658699355 seems to be same browser and managing fine

There have been a lot of updates from MS in the past two weeks or so , and some of them have been browser related apart from the usual Windows Defender updates.
BTW I am running Win 7 pro 64 bit at this time as I just don`t like Win 10.
As I have stated in an earlier post I will try going back a few weeks in windows to see if it reverts to what it used to be.

An exciting evening sat monitoring all the speed tests looking for unusual speeds now

Cannot expect to review them all but should be able to spot fast FTTC with slow upload

Tough at the top Andrew.

OK I have now reverted my system to 2/6/17 and the upload and download are now ok.
Have just done a speed test using the TBB new tester and my download is ok at approx. 74.4 Mbps and the upload is now about 17.2 Mbps..
Looks like in my case it was the MS updates to the IE 11 browser that was causing the problem.

Do not worry too much about it as it seems that some of the MS updates to the IE browser and the DotNet programs are the cause , at least in my case.
Trouble is that if a lot of users have auto updates on then they will get the DotNet updates installed and the browser updates.

Just run TBB speedtest again on Firefox Beta and it is reporting 16.9Mbps upload. Very muddy waters.

Forgot to add that FF had updated to v55.0b5 before the last speedtest.

I have had perfect results since putting windows back to an earlier date , so am satisfied that it was the MS updates that messed with my readings.
