votes

I created asp.net app for work with websockets
I published my app on IIS8 (server RAM 64GB, processor i7)
When I testing I can open 5000 concurrent connections
and then server dont wanted other open connections
When I increase the number of worker processes I can open more connections

But I'm wondering how I can increase a limit for one process?
