That is because subversion doesn't even know you are connected remotely
with the ssh tunnel. SSH logs in to the server, and invokes subversion
just as if you were logged on locally at the server. The server doesn't
handle any part of the login. When you run svnserve, it is listening
for connections and it must authenticate the user.

I think this is another case of wrong optimization. Optimize the
bottleneck first. Unless you have done some profiling and know that ssh
is chewing up a lot of time, then you are barking up the wrong tree.
I'll bet money that the extra cpu overhead that ssh adds is negligible,
but the only way to know for sure is to profile it.

Why not? It does what you need, so what's the fact that you're only
using it on a local network got to do with it? Also it frees you from
having to use the kludgey VPN junk to access the repository securely
from anywhere in the world.
