Web6 nov. 2024 · io_uring is a Linux API for asynchronous I/O. It is designed for higher performance than the older Linux AIO API that QEMU supports. In QEMU, io_uring is an alternative AIO engine. Instead of specifying -drive aio=threads or -drive aio=native, use -drive aio=io_uring. WebFor peak performance, io_uring helps us get to 1.7M 4k IOPS with polling. aio reaches a performance cliff much lower than that, at 608K. The comparison here isn't quite fair, since aio doesn't support polled IO. If we disable polling, io_uring is able to drive about 1.2M IOPS for the (otherwise) same test case. 参考 b is for bee worksheet https://ocsiworld.com
