What is more important and relevant to your streaming issues is single threaded performance, run a tbb speedtest or dslreports single threaded test next time you seeing problems. Also run some packet loss tests. speedtest.net isnt a very useful test as it can hide certain issues due to its high threaded nature.
Ok, I just did that shown below, but there was plenty of bandwidth left to use, I think its a Twitch issue, I don't think its a browser issue due to they all have this issue.
This is soooooo bugging me, and getting a tweet reply from
@TwitchSupport is impossible to do with this issue and they are aware of this issue.
I did at one point think it might be an IPv6 issue, but after packet sniffing I could see its using IPv4 so that wasn't the issue.
But what I can see is that Twitch just stops sending me stream packets and I just run out of buffer and this happens on (Edge, Chrome, Firefox) so its not a browser issue, this also happens on other machines on our network no matter what resolution sizes we choose.
And YouTube is absolutely fine even watching long 4K Streams, so our connection seems fine.
