    I am experiencing CPU usage issue when running Unet server (as Windows desktop build) with and without checked option "Use Web Sockets". It looks like the build is 20-30x slower with Web Sockets and profiler does not show nothing interesting. Do you experience same behaviour? Is it known issue?

    Same. Also windows build won't connect to server while using websockets, and WebGL player crashes if you feed it URL instead of IP address when trying to connect.
    Too much stuff to report here, we're not getting paid for this. QA should do their job sometime.

    BTW This happens only on a single core virtual server instances. The thing is that it always utilize entire core.

    It does not have to eat entire core just to poll the updates.
    Well if our .Net stack is too old for this, then at least give it like 1-5 ms sleep time between polls. I added it artificially and it was running just fine.

    I'm having the same issue with 5.4 - you can even see it in the Editor performance when running a server with webSockets on.
    Are there any news on this issue?
