Following up from my previous post, I think I've discovered what was
going wrong. It seems that either there is a problem with my server's
setup, or that there is some issue between Subversion/PySvn and Apache
that causes the performance degradation. If I run the script using
svnserve as the host, then everything remains at full speed. Everything
is now exported happily from VSS and into Subversion :)
For anyone who is interested in playing with the script I wrote, I've
uploaded it to my personal web server at http://jasonfield.com/ - follow

Cheers,
