The latest versions of git-svn should be vastly more space efficient
with .rev_map files.

Ah, that's because it started off in the /incubator directory, not /synapse:

$ svn log -v -r 234478 http://svn.apache.org/repos/asf
------------------------------------------------------------------------
r234478 | dims | 2005-08-22 05:39:51 -0700 (Mon, 22 Aug 2005) | 3 lines
Changed paths:
   A /incubator/synapse/branches
   A /incubator/synapse/site
   A /incubator/synapse/tags
   A /incubator/synapse/trunk

init synapse SVN

Can you try using the latest git-svn and also --no-follow-parent?

--no-follow-parent won't traverse copy history so it may be faster,
but you'll get an incomplete history.

On the other hand, it looks like the asf repo is hopelessly slow
for history retrieval.

I'm pulling the asf log (svn log -v http://svn.apache.org/repos/asf >
tmp.log) but it's taking forever...  git-svn uses basically the same
operation as 'svn log -v' and I've yet to see an SVN server take this
long to show history.

I've gotten 70,000 revisions after over one hour with the above svn log
command.  I'm going to restart this from a server with a better
connection since I need to power off this one when I sleep.
