yes. poll is the way better API, easier to use, easier kernel-side,

avoids a lot of problems (common!) improper use of select() brings, ...

using kqueue directly is painful. I'd recommend libevent if you really

want to go that route.

That said, kqueue really only pays out when you have _lots_ of

concurrent connections, say, >10000.

programming w/ libevent is convenient at times, the decision poll vs

libevent should not be made based on performance considerations,

exception beeing the above massive concurrent connection case.
