Subjectively, I'm not seeing any difference, but that may be due to a
relatively recent machine, and Austin's recent rebase [1] of Istvan's
database patch [2] no doubt makes a huge difference as well.


I've tried getting some hard numbers using

  #+begin_src sh
    time emacs --eval '(progn
        (notmuch)
        (notmuch-search "*")
        (while (get-buffer-process (current-buffer))
            (sleep-for 0.1))
        (kill-emacs))'
  #+end_src

... but the results vary wildly on subsequent runs.


How would one go about getting stable results?
