[WANTED: testers] Hi, after looking at some other things for a while, I made a patch to get 2.4.10-ac* to correctly eat pages from the cache when it is about pages belonging to files which aren't currently in use. This should also give some of the benefits of use-once, but without the flaw of not putting pressure on the working set when a streaming IO load is going on. It also reduces the distance between inactive_shortage and inactive_plenty, so kswapd should spend much less time rolling over pages from zones we're not interested in. This patch is meant to fix the problems where heavy cache activity flushes out pages from the working set, while still allowing the cache to put some pressure on the working set. I've only done a few tests with this patch, reports on how different workloads are handled are very much welcome: http://www.surriel.com/patches/2.4/2.4.10-ac9-eatcache regards, Rik -- DMCA, SSSCA, W3C?
