Yes. A real page fault hurts quite a bit, because all page faults go
via the host (which can swap out guest pages or have them COW).
I expect it to be even slower in 64-bit lguest, due to the added
complexity of the 4-level page table. But me and rostedt have not yet
made any benchmark for it _at all_, since we're mostly stuck trying to
make it smp ;-) (bugs, bugs, bugs)
Nick, are you willing to help us in 64-bit too?
got no 64 bit boxes (except PowerPC) so I guess we cna't do much on this
yet, but we should be getting some here soon.
