I forgot to ask in my previous email what the configuration was for this
netbench test. For example, was it a UP or SMP guest? Where did the netbench
clients run? Did you run with PV drivers?
The latter is particularly relevant, as measuring I/O performance of an HVM
guest without PV I/O drivers is particularly useful. Unfortunately I'm not
sure whether anyone has got the GPL PV drivers working with Server 2008 as
yet. But if not that would seem a more useful step towards w2k8 performance
than Viridian emulation, imo. I bet if you compare XP performance on
netbench with versus without the GPL PV drivers, the difference is more than
10%!
