I suspect this has to do with authorization checks. Back in svn 1.2
or so (?) we added security checks to make sure that read operations
which touch a bunch of paths are all 'readable' by the user. It ended
up being a big speed hit to mod_dav_svn, which was now doing things
like checking the readability of every-changed-path when returning an
'svn log'. I wonder if now svnserve is experiencing the same sort of
readabliity-check-lag now that it's grown its own path-based authz
feature in svn 1.3.... ?

(Incidentally, we ended up creating a new httpd.conf directive to
*turn off* path-based read checks to speed things up again. I wonder
if svnserve needs something similar?)
