TBB Speed test. Has it changed?

Recently, I have only managed a test result of just over 100Mb using the TBB speed tester. Until a month or so ago I was getting >200Mb. Other testers, like speedtest.net, Uswitch and testmy.net give me 210Mb any time of day. Even file download tests give me >200Mb, so I know my connection is fine.

I am concluding that there is congestion between me an TBB servers or they have reconfigured the test so my set up can no longer use it reliably?

Any ideas?

It would be a good idea to post the link to that result so we can see the shape of the graphs.

What product are you on? It sounds like FTTP.

There are multiple versions of our test, so posting a link to the results would help to identify which version you are using or used.

If this is Virgin Media and its 200 Mbps service then no sign of widespread issues as people are getting the expected speeds from us http://tbb.st/1464689002817010855 and http://tbb.st/146469359612764970838

Our test is more sensitive to congestion than some others, especially as some may opt to use servers internal to the ISP.

Mt connection is 200Mb/12 with Virgin Media, FTTN


Here is a speedtest I just did via TBB.

Okay well can confirm no changes have happened to the flash speed test,
http://www.thinkbroadband.com/speedtest/button/14646... shows the graphs that are actually more important than the numbers and suggests maybe a PC/Software issue

What does http://labs.thinkbroadband.com/speedtest give

Reason for thinking its not us is if we look at other users on the exact same version of test that you used we see
http://tbb.st/146469359612764970838 i.e. what you expect

Your labs.thinkbroadband link gave me 210Mb down 11.9Mb up. Latency was high at 31ms Bufferbloat C and E. It is worth noting that the test fluctuated between 190Mb and 225MB as it progressed. (The single-thread test struggled to get above 100Mb as it progressed) I do understand what you are saying about such fluctuations. Perhaps the test operates near the limits of my processor. I checked processor usage during the test. It never went above 88%.

My PC running Windows 10, although fairly old, has never had problems with the processor managing greedy tests.

Okay so suggestion is that something in the flash library and how our flash test operates is misbehaving on your particularly combination of software and hardware. We are seeing plenty of others with the same provider and the flash test still showing good results so sure its not anything we've done.

Guess we will have to leave it then.

I will just have to figure why, all of a sudden, my TBB average has dropped from >200Mb to just over 100Mb. The only change here has been a change of Windows 10 version, to the most recent.


Better result using Microsoft Edge. So, could well be a Flash problem in Firefox and Chrome.

Yes that looks right now, the single thread speed is to be expected with Virgin unfortunately, points to some potential congestion issues within the local neighbourhood network.

In the past as versions ebb and flow for the flash in different browsers oddities show up for some people and then they vanish, ie. oddities are introduced as security fixes are rushed out. This is why we are leaving flash behind.
