I now repeated the experiments with latest master and still see the
results I mentioned earlier.  That is, with the functions I gave
earlier, the release branch is faster than master by a factor of 20!

Could someone try to repeat with master _and_ release and post the
results?

(defun foo ()
  (interactive)
  (while (not (eobp))
    (c-end-of-defun)))

(defun bar ()
  (interactive)
  (while (not (bobp))
    (c-beginning-of-defun)))

(defun foofoo ()
  (interactive)
  (elp-instrument-function 'c-end-of-defun)
  (goto-char (point-min))
  (foo)
  (elp-results))

(defun foobar ()
  (interactive)
  (elp-instrument-function 'c-beginning-of-defun)
  (goto-char (point-max))
  (bar)
  (elp-results))

(find-file-noselect "../src/xdisp.c")
(switch-to-buffer-other-window "xdisp.c")

And in xdisp.c's window do M-x foofoo and M-x foobar.

Thanks, martin
