I would be *extremely* surprised if svnserve were not /significantly/
faster because for every transaction under svn+ssh, you have to:

1) open up an ssh connection
2) spawn a one-time svnserve connection on the remote box
3) shutdown the ssh connection (actually kill it to be precise)

It's worse than that, though, since certain svn actions require multiple
connections, which multiplies those three steps rapidly.

In addition, it is a known bug that svn doesn't reuse existing ssh
sessions (which ssh2 supports through multiple channels), so even that
minor improvement is unavailable...

Did you put all of the authorized_keys stuff on a *single line* as you
were told to? I use this feature all the time and have no problems
whatsoever...
