Times please. Also when you are updating how many files have changed
between the revision
you have locally, and the head on the repository?
If you do and svn update, followed immediately by another svn update
does it still take ages?
Also I assume you are not checking out the entire repository, just the
trunk.

This is to be exepcted, as svn provides features that cvs does not, and
requires these extra
administrative files to do so.
