Do systems with huge pages page in the move-them-to-disk sense I wonder? I assume they don't in practice because it would be insane but I wonder if the VM system is in theory even willing to try. Something I never completely understood in the paging vs swapping thing was that I think that systems which could page (well, 4.xBSD in particular) would *also* swap if pushed. I think the reason for that was that, if you were really short of memory, swapping freed up the process structure and also the page tables &c for the process, which would still be needed even if all its pages had been evicted. Is that right? -------------- next part -------------- An HTML attachment was scrubbed... URL:
