I not missed anything, not sure what you think I got wrong. I was actually defending your speedtester.

Although perhaps what isnt helping matters is why there is different speedtesters on here, I would think by now the flash version should be replaced with a equally functional html5 version that works in the same way, both multi threaded and single threaded testing. Also I think the guest speedtester should be the same way also.

Me too.

then why are you asking for test results?

streaming of netflix is single threaded. Easy enough to know just by watching live connections during the streaming.

Also when I deliberately did some QoS testing on my network to cap individual threads (like VM style QoS), netflix and every other streaming provider I tested was unable to exceed that cap, yet if they were multi threaded they would have been able to as it only applied per tcp connection.

To the OP of this thread I suggest reading this thread on the VM forums, it may give you some answers.

As you have just confirmed, you tested the services to determine the number of threads. These are obviously the test results I am referring to. I am asking because I have seen it is not true that Netflix is single-threaded so it would be interesting to see what's going on or where the difference lies.

Running both alongside each other is ideal for comparing changes in one version versus one that has had no changes.

Flipping to the html5 for all with just a link to the flash for those that still prefer it will be the norm shortly and the html5 will then also link back into the profile.

You will note that I did not say two full HD streams and did not specify source. So two 720p streams should be feasible.

BBC has a list of its bit rates at http://www.bbc.co.uk/rd/blog/2015-07-the-development...

Perhaps I should rate limit a connection to 2,4,6,8 and 10 Mbps again and see what does and does not work i.e. did this two years ago to see what did/did not work.

You said there is no reason it won't work, using one of the most popular services cannot suddenly become a reason.

The link you give confirms that the video bitrate alone is >5 Mb/s for 720p. More than 10 into 10 does not fit I'm afraid.

@Andrew
I'm looking at the results from both of your Flash and HTML5 tester ran in sequence and although speeds are within 0.2Mbps, the latency figures are markedly different.
The Flash version states <1ms while the HTML5 says 18ms
Flash
HTML5
Is there an answer as to why the values are so different?

In reference to iplayerhelp.external.bbc.co.uk/tv/hd_general:

What do you actually mean by �High Definition�

To be classed as "true" high definition, we encode in at least 1280x720 resolution or 720p. We use h.264 with a bit rate of 3.2Mbps and 192kbps audio. This means that streaming programmes in HD quality will put demands on your network connection.

Thanks for the outdated info.
