[ovirt-users] Poor guest write speeds

[Donny Davis]

Thank you for reporting back.

I don't have to use async with my NFS share. Its not the same comparison,
but just for metrics I am running an

 HP dl380 with 2x6cores and 24GB of ram, with 16 disks in raidz2 with 4
vdevs. Backend is ZFS. Connections are 10GBE

I get great performance from my setup.
