Hmmm, does not reproduce for me with a copy of that repository.

With the patch I posted earlier, the time becomes:

perhaps you need to run tip-create-local-branches.sh to create all the 
local branches? You can find it in:

  tip/tip .tip/bin/tip-create-local-branches.sh

(does/should the presence of local branches matter?)

My refs/remotes/mingo/ hierarchy has as many branches as you do in your
repository as local branches, and I presume you do not have these tracking
branches as I do because you are the upstream of this repository, so
overall we have about the same number of refs.  In the experiment, I did
"branch -a --no-merged" (notice -a), so I do not think the difference
should have mattered.
