That's when bzr does the actual job of accessing the branch meta-data
and getting the information you asked for.

Do you see the above in "emacs -Q" as well?

What do you see in ~/.bzr.log if you invoke

  bzr log -l1 gnus-group.el

from the shell prompt?  If you see the same 18 sec, does it help to
say

  bzr --no-plugins log -l1 gnus-group.el

instead?
