Epoll vs. io_uring in Linux

The discussion compares epoll and io_uring for Linux I/O, with commenters noting io_uring's lower latency and better scalability for high-throughput workloads, but cautioning about its complexity and maturity compared to epoll's simplicity and widespread support. There is consensus that io_uring is superior for modern, async-heavy applications, but epoll remains practical for simpler use cases.
