Hi.
I have an entry level server (Dell PowerEdge T30, 16 Gb RAM, 2 x 1 Tb SATA hard drives) on which I installed Proxmox 5.1 configured with a ZFS RAID1 pool.
I know this is a slow system, but after creating 3 virtual machines the server is terribly slow: continuous high I/O delay and CPU stucks on virtual machines when I make some high writes (for example restoring a mailbox or a database).
I know that upgrading to SSD should improve the performances, what about move to software RAID1?
Is there anything I can do to improve things?
I also tried to disable the ZFS sync, and this is my pveperf:
Thank you very much!
Bye
