git-push of new, tiny branch doing more work than necessary?

I've run through something quite like the following scenario a few
times lately:

	git pull origin
	git checkout -b experiment
	# hack a file or two
	git commit -a -m "new experiment"
	git push origin experiment

What I expect at this point is for git to push the few newly created
objects out to the repository. Instead it talks about generating,
deltifying, transferring, and unpacking thousands of objects (see
below).

Shouldn't the same WANT/HAVE hand shaking that makes git-fetch
efficient be doing something similar here? Or am I just doing
something wrong?
