Of course, there are also some files in /proc/sys/vm that you may want to
peek into, for tuning the swapping. Particularly, at later 2.6-kernels (I'm
running 2.6.12) you have the file /proc/sys/vm/swappiness, where the number
should be some percentage. I'm not completely sure how it works, but I
suppose that the higher you set it, the more likely it is to swap out
memory not beeing used. I think the default setting is probably sane, but
you may want to google a bit about it.
