Btw, do you know /why/ this was the case? I have a strong hunch this was because you moved some swap-out pages out of the way of the rest of the pages on the LRU list. The new VM, as integrated in -test9-pre1, does the same thing, only for a lot more cases than your classzone patch did, achieving the same effect, only stronger and effective in more different situations. Add to that page aging, and the drop-behind code that makes it possible to do streaming IO without putting memory pressure on the working set .... (well, not in all cases ... drop_behind() and read-ahead don't work for mmap() yet) regards, Rik -- "What you're running that piece of shit Gnome?!?!" -- Miguel de Icaza, UKUUG 2000 http://www.conectiva.com/ http://www.surriel.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
