On the graph here: http://www.kerneltrap.org/~npiggin/vm/4/
the x axis is the -j factor, and I'm compiling a 2.4.21
source with gcc 3.3 booting with mem=64M.

You can see it just starts to swap at -j6 and I'm going up
to -j16 which is then fairly heavy swapping (takes >20minutes).

Another thing that will need looking at is non swapping
pagecache performance of course.
