I'd suggest that the repo on the server should get a regular garbage
collect (daily, perhaps via cron) and on each release an aggressive
garbage collect.  It will be much easier on the server (reduced traffic
and fewer requests to serve).

Not only is the size of the repo much larger than it needs to be, the
server also has to deal with lots of small requests that can't be
efficiently transferred.  Cloning the repo via http protocol produces
190MByte on disk, a simple and fast 'git gc' gets that down to 63MByte,
just like cloning via git protocol (ironically, the server will do that
work on each clone as long as you do not do a garbage collect on the
repo itself).  An aggressive garbage collect takes a while longer, but
reduces the size of the repo down to 44MByte.

An http clone on repo.or.cz currently delivers 72MByte, so it appears
they do a regular garbage collect (or it simply comes courtesy of
mirroring).

Achim.
