yes, definitely. have you considered using NFS rather than zvols for the data filesystems? (keep zvol for the domU software.) it's strange that you see so much write activity during backup -- I'd expect that to do just reads... what's going on at the domU? generally, the best way to improve performance is to add RAM for ARC (512 MiB is *very* little IMHO) and SSD for your ZIL, but it does seem to be a poor match for your concept of many small low-cost dom0's. -- Kjetil T.
