Parts of Emacs tend to be slow because they depend on the speed on the
Elisp interpreter, which is pretty slow.  But usually that's not
a justification for being 60 times slower.  So please
M-x report-emacs-bug, showing the exact sequence of key presses
you used.  We might be able to speed things up significantly.
