I've also been playing with bzr and emacs repository. Many history
operations seem very slow but "bzr missing" is the worst:
$ time bzr branch -r -2 trunk test
[...]
real 2m8.822s
user 1m59.767s
sys 0m2.828s
$ cd test
$ time bzr missing ../trunk
You are missing 1 revision(s):

real 15m52.620s

sys 0m11.813s
Yes, almost 16 minutes.
