io_uring

io_uring is a Linux kernel feature that improves how fast and efficiently programs perform input and output operations, like reading or writing files and network data. It allows applications to submit multiple I/O requests quickly without waiting for each to finish, then receive notifications when they’re done. This reduces overhead and latency, especially in high-performance or server environments, by streamlining data transfer tasks and minimizing system calls. Essentially, io_uring makes data operations faster and more efficient by handling multiple requests asynchronously, enhancing overall system responsiveness.
