I fought with this a few months ago when I did my own clone of gcc svn.
My bad for only discussing this on #git at the time. Should have put
this to the list as well.
If anyone recalls my report was something along the lines of
git gc --aggressive explodes pack size.
git repack -a -d --depth=100 --window=100 produced a ~550MB packfile
immediately afterwards a git gc --aggressive produces a 1.5G packfile.
This was for all branches/tags, not just trunk like Daniel's repo.
The best theory I had at the time was that the gc doesn't find as good
deltas or doesn't allow the same delta chain depth and so generates a
new object in the pack, rather the reusing a good delta it already has
in the well-packed pack.
Cheers,
Harvey
