We're running a Subversion server on a Linux VPS over HTTP (so the URL is http://repository/svn/project/trunk) but it is stupidly slow. By slow I mean at most about 4KB/s checkouts and checkins. Test downloads from the VPS seem to be just fine.
Where would I start looking for information on this?
FWIW it's running Ubuntu 8.04 and Linux 2.6.18 (yes I know that's old).
