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

HI ! here are some preliminary benchmarks of lguest vs host (2.6.21) Most results seem resonable - the file create/delete is a bit strange - does anybody have an idea why 0k file create/delete could be so much faster under lguest and 10k file so much slower ? The only really serious
