Please note that git downloads all 51 branches that exists or existed on
Savannah while bzr gets just `trunk'.

Git keeps the pipe downloading data at full speed all the time, while
bzr fluctuates a lot, including several long pauses, possibly because
the server is doing some CPU-intensive work for preparing the data.

Maybe the differences are not big enough to notice by most people that
update their Emacs mirrors from time to time, but it is not accurate to
say that bzr's network protocol is no less efficient than git.
