Certainly throwing more RAM at it will speed things up, but I was hoping
for a solution involving some clever thoughts and ideas about how to
minimize disk accesses on the client when doing update and status
operations. I would very much not like our developers' first experience
with subversion to involve deciding on whether or not to go to the
restroom while the status finishes. :) That would not be a good first
impression. Any ideas other than throwing more hardware at it? I, for
one, am willing to work around 1 minute status and update because I
already know of the other amazing advantages of SVN, but a newbie to SVN
may reject it or become bitter towards it right off the bat and I want
to avoid that.
