At least 16GB of RAM for the vast amount of disk cache that will give
you.  32GB or more will mean you can easily put the TMPDIR or WORKDIR
into a tmpfs (there's been discussion about this a few weeks ago).
I've 16GB of RAM and a 8GB tmpfs with rm_work was sufficient for
WORKDIR which gave a 10% speedup (and massive reduction on disk wear).
 Others have machines with 64GB RAM and use it for all of TMPDIR, at
which point you'll be almost entirely CPU-bound.
