I have a server running Proxmox and some Linux VMs running on it.
- On the host, I get 200+ MB/s write to the disk
- On a VM, I only get around 50-60 MB/s
Caching is disabled for all VMs. I'm using Virtio-SCSI as storage controller
Specs of the server:
SuperMicro 5018R-WR
Intel Xeon E5-2620v4
64GB memory
4x 1TB WD RE (WDC WD1003FBYZ-010FB0)
Software RAID 10 + dmcrypt + lvm(thin)
I know that mdraid is not supported by proxmox, but as I get the full speed on the host, I don't think that's the problem.
Any hints would be very appreciated.
Thanks, Patrick
