[ovirt-users] Poor guest write speeds

You can run without async so long as your nfs server can handle sync writes
quickly

Hi Donny (and everyone else who uses NFS-backed storage)

You mentioned that you get really good performance in oVirt and I am curious
what you use for your NFS options in exportfs?  The 'async'
option fixed my performance issues, but of course this would not be a
recommended option in a production environment, at least unless the NFS
server was running with a BBU on the RAID card.

Just curious.  Thanks! :-)

-Alan
