With -Q:
Emacs 22: ~0.4s
Emacs 23: ~0.7s

Even here, Emacs 23 is noticeably slower.

With a one-line .emacs, (desktop-save-mode 1), and starting with
--no-site-file, the timing for Emacs 22 was essentially the same (~28s,
but I was a bit slow typing 'y' to ~5 prompts for File local variables
and hi-lock-mode's fonts).

Emacs 23 threw an error after loading ~15 files.  The error was
"c-define-lang-constant: `c-lang-defconst' must be used in a file", which
is one of mine.  :-(  But the loading of the files seemed just as
sluggish.

It doesn't seem like it's anything in my .emacs/site-start.el causing the
slowness.
