This 50% loose has nothing to do with the new backup algorithm, because your test does not involve any writes. So it is more likely a bug in the AIO code. I will dig deeper next week. I wonder if such slowdown also happen with other KVM block jobs (storage migrate). _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com http://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
