Stop Reaching for io_uring. The Kernel Is Already Smarter Than You
The tech world treats io_uring as a magic wand for performance, but a state-of-the-art async I/O interface is often the wrong tool for the job. When doing contiguous reads, the kernel’s existing readahead and page cache frequently beat io_uring. Stop fighting the kernel, drop the O_DIRECT obsession, and match your I/O primitive to your actual access pattern.
