Linux I/O Models and io_uring Performance Overview

Linux I/O models range from synchronous native operations to asynchronous kernel‑bypass techniques, with APIs such as open, read, write, mmap, sendfile and splice, while the modern io_uring interface—supporting interrupt, polling, and kernel‑polling modes via liburing—delivers superior performance, especially at high queue depths, compared to traditional libaio.

High‑Performance Network Solutions: RDMA, RoCE, iWARP and io_uring – Principles, Implementation and Benchmark Analysis

The article reviews high‑performance networking options—RDMA (including RoCE v2 and iWARP) and Linux’s io_uring—explaining their principles, hardware requirements, and benchmark results, and concludes that while RDMA delivers ultra‑low latency for specialized workloads, io_uring offers modest network benefits, leaving TCP as the default for most services.
