That's what I do, with slightly different values. But the machine kept swapping before the upgrade, so maybe it was really short on ram. Thanks though.

If you don't want to use swap, try decreasing vm.file{max,min}. For example on my server, I use vm.filemax=5 and vm.filemin=0, hope that will help you.

I haven't seen it swaping any more since the upgrade, and I've built the whole KDE and run multiple CVS update processes (even concurrently); these two operations together use lots of files and memory.

Ok, I actually have vm.filemin=5 and vm.filemax=10 in /etc/sysctl.conf (2 and 4 respectively on other machines), so that might be the difference with your system. The defaults for those two variables are too big.

No question going from 256 to 2Gb made my laptop hum! -but UVM is still a queen bitch sometimes, cvs update (even with all cvs/Root linked to one file) is deadly to other processes, dump|restore pipes cream the machine, its far from easy to understand the VM tuning implications of being self-hosted on one box, depending on X as well as shell, and then wanting to thrash the bejazus out of it compiling or walking the FS looking/touching many small files.
