I shaved about 30% off the time - the patch is waiting for 1.8.1, but you can try it now (see the ticket for the changeset):

I've added you to the ticket so you can follow what I'm doing. Getting any further improvement will take a little longer due to travel and vacation, but I'll keep poking at it.
