I've heard lots of good suggestions already - another thing that I've not
seen mentioned is, upgrading your kernel may help.  Somewhere shortly
before kernel 3.0, pathname lookups got noticeably faster.

You could also try an alternative filesystem like xfs.  It's supposed to be
pretty good at large directories.
