Hi list, I'm doing some speed benchmark between
drive-mirror vs qemu-img convert , and drive-mirror seem to be a lot slower. test: convert 1 32GB qcow2 file to raw file, local storage (6 disk 15k in raid10 + raid BBU cache) time result: qemu-img : 30sec drive-mirror (vm is paused, no writes) : 5min Any idea why drive-mirror is so slow ? (maybe does it use directsync when mirroring ?) I think both should have around same speed ? Best Regards, Derumier Alexandre
