(Whoa -- any idea why?  Are you getting bounce messages?  I think you're
right, as I don't see your mail in the list archives.)

Happy to forward when needed.  But in this case, I'll just make sure to
quote all of your mail in my followup, so all your words are here.

Thanks.  Glad to hear it, especially as my attempt to fetch the old
repository just failed:

  $ mkdir emacs-new
  $ cd emacs-new
  $ bzr init-repo --2a .
  $ time bzr branch http://bzr.notengoamigos.org/emacs/trunk/
  bzr: ERROR: not well-formed (invalid token): line 16, column 56
  real    522m9.865s
  user    415m13.049s
  sys     1m7.948s

That was part of a test before I responded to Cheng Gao's message of
http://lists.gnu.org/archive/html/emacs-devel/2009-08/msg00350.html, in
which he reported this:

  $ time bzr clone http://bzr.notengoamigos.org/emacs/trunk/ emacs
  Branched 95203 revision(s).                                                   

  real  193m58.965s
  user  6m58.284s
  sys   1m12.954s

But since you have a new branch now, I'll just test with that.

I will compare the time to 'bzr branch bzr://...' against the time to
fetch a tarball over HTTP.  However, one thing we might want to try is
offering the bzr sources via HTTP as well.  In fact, maybe you already
are?  After this current branch via bzr://, I will try it again using
http:// (note that's what Cheng Gao used -- and his use of the "clone"
command instead of "branch" makes no difference, as they are synonyms).

What kind of Net connection does bzr.notengoamigos.org have, by the way?
(I'm doing my 'bzr branch' from a server with a very wide pipe, in order
to remove my home Net connection's speed as a factor.)

No need to apologize -- thank you for making time for this!
