Repeating the experiment I get similar results with (22.0.50):
emacs
emacs -Q
emacs -D
emacs -Q -D

except that these are twice as fast as my previously posted result and the
user experience varies (emacs -Q seemed slower than emacs -D). I'm not
familiar with elp, but I imagine that there is some skill in understanding
the results and in doing a control test.
