WebInnoDB uses the asynchronous I/O subsystem (native AIO) on Linux to perform read-ahead and write requests for data file pages. This behavior is controlled by the innodb_use_native_aio configuration option, which applies to Linux systems only and is enabled by default. On other Unix-like systems, InnoDB uses synchronous I/O only. 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
