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? thanks! -- Glauber de Oliveira Costa.
