Continuing to work on improving clone times, using "git gc
--aggressive" has resulted in a large number of tags combining into a
single file but now I have a large number of files in the objects
directory - 131k for a ~2.7GB repository. Any way to reduce the number
of these files to speed up clones?

Can you paste "git count-objects -v"? I'm curious why gc keeps so many
loose objects around.

An easy way to get rid of them is to clone the non-local way.
Everything will be sent over a pack, the result would be a single pack
in new repo. Try "git clone file:///path/to/source/repo new-repo". You
can also try "git prune" on the existing repo (read its man page
before use).

Presumably ejected from the pack because they are now unreachable.
That's a rather large number, but if there was recent ref maintenance
(e.g., deleting branches or tags), it is not impossible.

If you have git v1.7.12 or greater, you can also use the "--no-local"
option to clone. But as you mentioned, pruning is probably the most
sensible thing (and for a non-local clone, those objects should not
impact performance at all, as we will never even look at unreferenced
objects).
