Nice. That's a really impressive improvement. I've been adding io_uring test cases for automated performance regression testing with mmtests (open source). I'd love to take a look at this test case and adapt it to mmtests, so we can pick it up and run it frequently. is it something you can share? -- Gabriel Krisman Bertazi
