Just an observation. When I ran pack-objects with irrelevant commits removed (i.e. try_to_simplify_commit) on Documentation/, I got a 6MB pack. When I ran it without commit simplification, I got 16MB pack. That's 10MB larger. Now I don't how much of that 10MB share is commit messages, authors, committers and trees but I suspect trees take a large part in it. Maybe you can just fake the trees in those fake commits as well, to avoid downloading more trees. -- Duy
