Honnestly, if you're using threads (I mean lots of threads, such as one
per connection), I don't think that poll performance will be your worst
ennemy. The first thing to do is to handle the task switching yourself
either with a publicly available coroutine library or with one of your own.

Take a look here for more a comparison of several available methods :

epoll is compared to other methods with numbers here :
