A faster hard disk (on the client) is what you can throw at it:
Subversion is extremely I/O bound.
Other than that: use 'checkout' as little as possible: getting
secondary copies works great by making local copies of your working
copy and then 'svn switch'-ing to the branch. This retrieves deltas
instead of full files, updating only those files which have actually
changed.
HTH,
Erik.
PS: Lots of other operations should have become faster, but checkout
is what builds the base to be faster and that takes extra time. You
could investigate 1.5-alpha1 (out in a few days), which supports the
Serf HTTP/1.1 library. We have observed interesting speedups with that
library (when compared to the pre-1.5 non-Serf behaviour).
