I compared it with FreeBSD kqueue, epoll and kevent_poll (this is generic poll/select notifications ported to kevent) based (it is the same server but with different event functions. Client was httperf, I ran it with 30k connections in bursts of 3k connection with 1 second timeout between bursts. Here are results: kevent: more than 2600 requests/second epoll and kevent_poll: about 1600-1800 requests/second kqueue: enormous number of connection reset errors (only 62% of successfull connections) (likely misconfiguration, default FreeBSD 6-something does not allow such rates at all).
