Epoll vs. io_uring in Linux

Epoll and io_uring are two Linux APIs for handling I/O operations. Epoll is a traditional API, while io_uring is a newer, more efficient one. io_uring is designed to provide better performance and scalability. Engineers should consider using io_uring for new projects, but may need to stick with Epoll for legacy code. Upgrading to io_uring can improve system performance.
