Also, upgrading git to 1.5.6.2 might be a good idea. It doesn't use the .revdb file format anymore, but a more efficient .revmap file. And it has quite a few performance improvements (although they won't help against the primary issue with that svn server). Don't use 1.5.6/1.5.6.1, they have a git-svn bug that can lead to corrupted clones (just in case that your distro has packages for those versions but not yet got 1.5.6.2).
