It is.  Looks like python-nav--forward-sexp is indeed the main
culprit.  To narrow this down even more, I suggest to load python.el
(not .elc!) manually into a new Emacs session, then repeat the
experiment, and show the profile below python-nav--forward-sexp.  This
might point out the part of that function that takes the lion's share
of the run time.

Thanks.
