The io_uring subsystem is becoming a game changer for Linux developers, allowing for faster I/O performance and a more natural event-driven programming style.
- Unlike the older AIO subsystem, io_uring uses a shared memory ring buffer between user space and the kernel, enabling it to submit operations and collect results without requiring slow system calls.
- Developers are taking notice of the potential for improved performance and rethinking the way they design Linux applications.
- While io_uring is still new, it has proven itself in small areas and is likely to become an essential tool for high-performance computing, web servers, and DBMSs.
