So on my machine the entire git history is just 1.8G; that's because the history is very densely packed on the server and pulling the entire history does not require an unpack-repack-send sequence. But if you download a partial history, then the git server has to unpack and then repack the required history in order to send it; that makes the process much slower and results in far more data being transmitted (the on-the-fly repack is not as dense because it would take too much time).
