As per this thread http://kerneltrap.org/node/view/3000 and the resulting hoopla on slashdot -- it'd be nice to have an easy gui tool for tuning the kernel's preference for swapping. A lot of people disagree on what the correct policy ought to be -- and indeed, it's different for a lot of situations -- so having it tunable via the gui program seems desirable.
There's now a more detailed story on this on LWN -- <http://lwn.net/Articles/83588/>. Seems likely to be one of the most popular values to tweak.
sorry but s-c-proc is now deprecated...
Oh. :) Is it replaced by something, or is there a new magical thing which automatically does the right thing for all situations and makes all people happy? :)
