[PVE-User] proxmox-restore - performance issues

[Gregor Burck]

Hi,

it is PVE and PBS on the same machine, I wrote it on my first mail ;-)

an additional information:

I made in the moment a new test aftar an reboot to exclude to much RAM
iisues on the zfs cache.

With 6 jobs the total io I see over iotop alter between 120MB/s and
240MB/s with peaks of 300 MB/s
When I start htop I see work on all cores but no core is on 100%

and the benchmark:
