This technical article compares three different approaches to building an HTTP file server: synchronous thread-per-request, epoll-based asynchronous I/O, and the newer io_uring interface. The author provides code examples and implementation details, starting with a baseline synchronous server and then exploring more advanced I/O methods. The article offers valuable insights into performance optimization and modern Linux I/O techniques.
Background
The evolution of I/O models in Linux has progressed from traditional synchronous approaches to more efficient asynchronous methods like epoll and the newer io_uring interface, which aim to reduce system call overhead and improve performance for high-concurrency applications.
