> I keep my swap on, but set swappiness to 0. Been working great that way. Yeah but with that patch that changed the vm system behaviour, setting swappiness to 0 had ZERO effect. The kernel happily swapped out what data it could from programs that were running. This blinking patch gave the impression that Centos 4, that is RHEL4, was slow compared to RHEL3 and the Fedora distros. I don't understand why the fix will wait till 4.4...
