Look at the file lisp/loadup.el.  Those are the Lisp files that are
bound into Emacs.  A lot of Emacs' size is due to the "Pure lisp
storage" that houses those bound files.  If you can, you can try to
reduce the size of the pure store (do a grep for PURE and SIZE).

Gzexe is another way to reduce transfer time.  If your processor is
decent, it will not affect execution time much.

Don't compile in Mule support.
