Description

Using autoversioning, you can quickly get big revisions.

It is basically taking 0.1s per 1000 revisions to pull the log from
the repository
  time svn -v --xml log -r 3000 file:///usr/svn_old
real    0m0.370s
  time svn -v --xml log -r 5000 file:///usr/svn_old
real    0m0.548s
  time svn -v --xml log -r 15000 file:///usr/svn_old
real    0m1.405s

Current workaround is to svnadmin dump and svnadmin load into a fresh
repository (obviously loosing revisions - although this is not a
disaster as I'm using subversion as revision controlled filessystem
with dav_fs and mod_dav_svn)
