Hi I just picked up a refurbished DELL RACK MOUNT POWEREDGE R820 4 X XEON - E5-4607 2200 192GB Ram. Latest Proxmox installed and updated. (5.4) 8 x 3TB 2.5" HDD Raid Z2 zfs.GUI shows total 48 cores. Doing some testing, installed Windows 10 pro and Windows 7 Pro. Both are running like "dogs". To make them usable I have had to run each with 16 cores and 36GB ram. To restore a 90GB backup (200GB VM), it took 133 minutes On a dell R710 Dual processor same restore takes 26 min. Any suggestions ???
