bzr should be showing traffic activity, according to your log 13MB of
data is copied in that 400 second window.

It appears to return a single 13MB section, then a stream. Thats a
pretty large block of data. It may not be possible to sensibly break it
into smaller bits, if it is the revision graph (and I suspect it is) -
but we don't need smaller bits to show a better UI.
