    pve 4.2 and iothread

    Hi all, I have done some IO tests on proxmox 4.2 with iothread. Results below: fio --description="Emulation of Intel IOmeter File Server Access Pattern" --name=iometer --bssplit=512/10:1k/5:2k/5:4k/60:8k/2:16k/4:32k/4:64k/10 --rw=randrw --rwmixread=80 --direct=1 --size=4g --ioengine=libaio...

When I backup the same virtual machine using stop-mode backup, it...
