My own feeling is that font-lock.el works fast enough
That was only an example for displayed-related stuff in Emacs Lisp.
If there is no problem with font-lock and updating buffers after change
etc., the better.
So my impression, a remarkable amount of reports deal with slowness of
display/re-display were wrong.
There have been quite a lot of (justified) complaints about the slowness
of C Mode's redisplay. These wouldn't be helped by rewriting
font-lock.el as font-lock.c. They might be helped by rewriting parts of
CC Mode in C. This has already been suggested (by Eli), but hasn't been
explored in any great detail, as yet.
