Thanks Andrea,
after applying the patch, I repeated the experiment. Since the cat /dev/dvd >/dev/null no longer really made any difference, I started at the same time a dd if=/dev/hda2 of=/dev/null (a 6 GB partition) and eight find / processes at slightly difference points in time (to excercise the same disk blocks repeatedly). I let the whole thing run for about 5 times longer than the original test, and while the system still pushed a lot of programs onto swap (from an initial used memory of 190 megs, up to 80 was pushed onto swap while I kept "using" most of the programs by clicking on buttons etc), the system remained fairly responsive (a couple of individual apps became sluggish enough to categorize as unresponsive, but a couple of other programs kept responding almost as well as in a no-load condition). To top it off, I tried to play some .ogg files with XMMS - there were breakups in the output every 10-15 seconds, but other than that, XMMS worked fine as well. I don't run XMMS with realtime priority, so that might have fixed even the sound output problems.
I'd have to say I now (finally!) have a kernel which doesn't eat up all my memory.. :) For the record, the setup now is 2.4.10 + rml-preempt-kernel-1 + aa-vm-tweaks-2.
Cheers,
Osma
