Hello, I have new HPE DL360 with proxmox and Synology NAS RS2418+.

I trying migrate my VMs from backup which they are on different (old) NAS to new proxmox installation where I use iSCSI target.

1. I created LUN and Target on NAS.
2. add iSCSI to proxmox
3. add new LVM to proxmox storage. Volume group is synology iSCSI

But transfer to iSCSI LVM is very slow. 5 GB backup file around 30 minutes. If I restored the same VM to local_lvm it was around 60 seconds.

Where could be a problem?
