Did you do that from the public Biopython CVS server to your machine?
If so, its nice to know that step isn't too slow.

Have you got a feel for whether it would be easier to sync CVS and
bzr, or SVN and bzr?

I personally would be more interested in an automatically synchronized
git repository (rather than bzr), but this is not a thoroughly
researched opinion.  As you pointed out, the poor bzr benchmark speeds
may not be so bad in the latest code - although the Biopython code
base is not so big that this really matters.
