This may go away after some time. When you start windows there are lots of zero pages, easy to share. Later on win actually starts using these pages, and it shares alot less. So it might be false goodie, watch it closely. It'd be interesting to see how it really performs on your case. For cache=off, I highly recommend using raw partitions (or LVM logical volumes) instead of files for disk images - if you don't do that already. And speaking of storage, if you use some sort of raid (except raid1, but _especially_ for raid[456]), ensure proper alignment of everythg. /mjt -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
