Done, it is standard practice for git :)

Jakob sent some patches a few months ago which seem to address the
issue. Unfortunately we forgot about them :x
Can you take a look at the following two "mergeinfo-speedups"
in my repo? (git://bogomips.org/git-svn)
Jakob Stoklund Olesen (2):
git-svn: only look at the new parts of svn:mergeinfo
git-svn: only look at the root path for svn:mergeinfo
Also downloadable here:
http://bogomips.org/git-svn.git/patch?id=9b258e721b30785357535
http://bogomips.org/git-svn.git/patch?id=73409a2145e93b436d74a
Can you please give them a try?

IIRC, the caching is unique to mergeinfo, so perhaps Jakob's patches
help, there, too.
Sorry I don't understand the mergeinfo stuff more, I've never worked on
a project which uses it.
