Re: timing Emacs 21 (was: comments on ntemacs 21.0.91)

[Robert J. Chassell]

   No, the code Bob posted invokes forward-* functions directly, without
   any sit-for.  Andrew's original code used an intermediate function
   that indeed called (sit-for 0), but not what Bob did.

   Bob, am I right?

Yes, you are right.  When I read the first message, I hurriedly passed
over the comments on redisplay and got curious about the various
forward-* functions, some of which search for regexps.

It should be easy to reinstrument the code for (sit-for 0).
If I have time tomorrow, I will try it.

Gerd wrote a very good message explaining why the lower-level parts of
redisplay have inevitably become slower because there is much more to
do.
