Question / Help Is Twitch rate limiting the download stream but not up?

Now I have to say that I'm doing this for testing mainly so I can understand stuff and such.

So picked Twitch for a bit of streaming testing and saw this guide.

https://help.twitch.tv/customer/portal/articles/1253460-broadcast-requirements

So 3500 is the max Ok I got 5Mb upload no problem so I start streaming no packet loss reported by the OBS and I run a continuous ping to my ISP WAN gateway and DNS server again no packet loss and ping is good. At the same time I load to view my streaming on another PC to see how stable it is...not very it just buffers and this is with no packet loss and ping is good apart from the download stream that is.

So I streamed a bit with NetWorx and to get some idea of bandwidth happening of the two this is the result.

I should point out I can stream other videos with higher bitrate just fine from Twitch but not my own at 3500. However If I run at 2500 then I can stream and watch it fine but why is this? Could it be that I have not signed up for turbo at twitch? But I can't seem to find info that if you don't sign up for turbo you should stream at 2500 so people watching your stream will not buffer and both PC's are capable of each running download streaming twice this much.

So I'm hoping someone knows more about this if not just another read about streaming at a given bitrate.

The ones you are able to watch at 3500 are being served by the global content network for twitch, the ones you aren't are being served out of san fransisco

Ok a hate windows for removing the custom TCP window size like XP did and I disabled autotuning because I would like a fixed TCP window size as a result its the latency now had stupid MS given me the option to change the TCP window size which applies to per TCP connection so it will stack in speed.

I would of never of had this problem I guess you can point the finger at me but I still blame MS for removing that setting.


Thanks
