True.  I haven't tried mercurial.  But I will say that the
memory and space requirements (in addition to the better speed)
of git have displaced bzr on my list currently.  Git has a
a steep learning curve, but here are some space numbers that
make up for it IMO.

  $ du -sh /data/src/mirror/*/*
  43M     bzr/SAMBA_3_0_23.bzr
  42M     bzr/SAMBA_3_0_24.bzr
  53M     bzr/SAMBA_3_0_25.bzr
  56M     bzr/SAMBA_3_0_26.bzr
  99M     bzr/SAMBA_3_0.bzr
  58M     bzr/SAMBA_3_0-lightweight.bzr
  60M     bzr/SAMBA_3_0_RELEASE.bzr
  312M    bzr/SAMBA_4_0.bzr
  257M    git/samba
  558M    svn/samba

The git repo is a full mirror of the svn repo starting at r1 and is
almost 1/2 the space of the svn repo.  I might could squeeze some
more space savings with various pack options.

The git tree I posted has the 3.0.23 - 3.0.26, 3.0 and 4.0 branches
and is less than 100M (1/3 of the SAMBA_4_0 bzr mirror alone).  And
to pull that tree at home (basic broadband) is about 3 minutes.

  $ time git clone git://git.samba.org/samba samba-test.git

If we were to swap to git, the full svn import would be < 160M
so the pull be only be slightly longer.
