Hello, I'm not an openstack user myself, but did notice when I was testing with proxmox if I set AIO to native vs io_uring it performs faster in Windows. We don't use Windows normally, so this was just a test environment and don't know if Openstack has something similar. Just my 2 cents for what little it's worth.
