Just to throw in a data point here - I have a repository here which is
under Perforce, with ~2.3GB working copies. Perforce keeps no
metadata whatsoever on the client side. Many operations are
unpleasantly slow, and the major bottleneck is funneling data over the
network. So I think Subversion's tradeoff is probably a good one even
with very large repositories. (I haven't tried Subversion on this
workload, though.)
Have you considered storing the text-base files compressed? It would
be pretty easy to implement - you've already got zlib in there - and
save quite a bit of disk for only a small speed penalty.
