epoll
epoll is a high-performance I/O event notification system in Linux, essential for handling
large-scale asynchronous network operations in server-side game development. Unlike select
or poll
, it uses an event-driven model, reducing CPU overhead and improving scalability.
Game servers leverage epoll
to efficiently manage thousands of concurrent connections,
responding only when events occur, minimizing system calls, and optimizing resource
usage—making it ideal for multiplayer games and real-time applications.
