Yep, if you see swapping, more RAM is probably the single most effective
performance enhancer you can possibly throw at it. The slowdown from
swapping to a spinning disk completely swamps all performance
differences between CPUs, for instance.

FWIW, the next thing to improve depends on your common tasks: a solid
state disk and a better video card are usually the best bets. The SSD
is great for compiles, program startups, and other disk-intensive
processes. (Get a good one, the cheap ones are awful.) The video card
is most useful if you do 3D, watch videos, or have a desktop that uses a
"compositing engine". If you just use twm to run xterms, it's not all
that valuable. :-)

Still, both of those are WAY further down the list than getting enough
RAM to do the compile in main memory.
Well I bumped up the RAM to 1GB and got more CPU share (this is a VPS at slicehost) - Rakuda built in 15 minutes or so. After it got built I bumped it back to 256 MB. I'm off to play with rakudo...
