Unraid as a VM on Proxmox, bad performance

[nikkyflax]

Does anyone run Unraid as a VM on Proxmox?

 

Dont know if I should post here or on Proxmox forums.

I have always run Unraid as a VM on Proxmox without issues. I have recently changed the hardware on the Proxmox host to server hardware from gaming hardware and I now experience bad performance to the disks. Before the change I could download Linux isos with SABnzbd in docker to my cache disk which is a LVM disk located on a nvme drive and the performance was steady. download performance was good and steady. even after download completed it was quick to move the iso to correct place.

Now after hardware change the disk performance is so bad. download speeds jumps between 0 and 100 MB/s all the time, never a steady download and when its downloaded it take between 15 and 30 min to move a 10 GB file over to the array. 

 

Running diskspeed on the cache drive shows 1.2 GB/s

Anyone has any experience with this types of error?
