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%! -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
