We are running 2.4.2pre4 on the penguinppc server with 512MB ram and only 384MB
of swap. Even serving lots of memory eating rsyncs.

This is the same amound of swap we were using with 2.2 and memory usage is
about the same in our situation.
I guess picking the amount of swap you need is a case by case thing. On my
machine at home I have 192MB of ram and if I compile mozilla while running
gnome and doing some web browsing I will swap like mad (much more than in 2.2).
I am current using 512MB of swap space at home in case I want compile KDE or
something because I have a feeling it could all get soaked.
The biggest problem is that most pmac IDE controllers perform poorly in Linux.
I am not sure if this is the fault of our drivers or the Apple hardware or both
but swapping 20MB of memory on the fly gives you a real performance hit. (Much
more so than doing it on an x86 with a well supported ata66 card).
