The Linux kernel implementation of epoll() system call is highly efficient because it can let a single-thread producer (e.g. the TCP/IP stack) provide data to multiple consumers (e.g. different user-space applications using TCP sockets) and immediately wake up the corresponding application to start consuming the data. Compare this implementation with different user-space alternatives, in which a user-space thread is the producer and need to wake different user-space consumers.
