Hm, I'd like to stay with 2.4, I don't like when my machine crashes and I don't have much time to try new kernels all the time...

Rik van Riel's rmap patches might help you greatly.

I've tried it in january and IIRC it gave me crashes within a day or so (or MOL crashed shortly after startup); someone said then "stay with a Benh kernel" which I did; later I've settled to the stock 2.4.17, .18 kernels and others. Currently I'm running (to my own surprise, I don't remember why I booted this one) a (stock?) 2.4.17 kernel, which has provided me the longest period without a reboot now (on a Powerbook G3 lombard).

So I'd like to change the least possible to get a good interactive performance, and think a general latency solution would benefit me more and be less invasive.

Christian.
