Yes, the byte-compiler has been changed slightly (some broken optimizations
have been fixed, mostly), so that can explain the little difference.
But still Emacs-23 with Emacs-22's font-lock.elc still takes 3.9s for
font-lock-fontify-keywords-region compared to 2.2s under Emacs-22.
So some of the underlying primitives have slowed down significantly.
Could you show the value of font-lock-keywords in that buffer?
