Epoll
epoll is a Linux kernel system call, a scalable I/O event notification mechanism, first introduced in Linux kernel 2.5.44. Its function is to monitor multiple file descriptors to see if I/O is possible on any of them. It is meant to replace the older POSIX select(2) and poll(2) system calls, to achieve better performance in more demanding applications, where the number of watched file descriptors is large (unlike the older system calls, which operate in O(n) time, epoll operates in O(1) time). epoll is similar to FreeBSD's kqueue, in that it operates on a configurable kernel object, exposed to user space as a file descriptor of its own.
