Comment (by devans@…):

 Replying to [comment:13 ryandesign@…]:
 > I tested on a gigabit Internet connection in Austin and it fetched 198MB
 in under 2 minutes. I've taken the Snow Leopard builder offline to test
 fetching there with the `--verbose` flag, and so far it's fetching at
 around 50KB/s; at that rate, it should take around an hour to fetch it
 all.
 >
 I just did another fetch here and the download rate varied from a low of
 25KB/s to a max around 256KB/s -- nothing more.  So I'm assuming Launchpad
 has a fairly slow connection or their host is really loaded down.  In
 addition, it looks like the bzr protocol is fairly inefficent -- lots of
 small packets with handshakes in between which doesn't help either.
 > So as I said in #49759 for git, we should modify MacPorts base so that
 bzr fetches print something while fetching. It looks like the `--verbose`
 flag only works in a terminal, so I'm not sure how to make bzr print
 progress information when called by MacPorts.
 Worst yet the bzr checkout command doesn't accept --verbose according to
 the docs.  Although it does show a progress bar when connected to a
 terminal.
