I did not manage to make a mirror first, but that's definitely what you 
would want to do (if you want to do it for another repository). 
Importing numpy took around 3-4 hours, that is 3-4 seconds / revision, 
mostly because of network latency.

With matplotlib, which I tried to, I first did a svn mirror, and then, 
it can import around 4-5 revision / second on average (of course, it 
depends on the changeset for each revision).

For bzr, once you manage to install bzr-svn, importing is transparent:

bzr branch http://blabla/trunk

You can also import the whole repository (including branches and tags), 
using the svn-import command, but that's a bit more difficult, specially 
if the repository does not follow the trunk/branches/tags convention of 
subversion.

cheers,

David
