I see it. On my setup, doing line-by-line scrolling, Emacs 22.1 is
able to scroll a large file (for example, lisp/ChangeLog) keeping up
with the keyboard typematic rate without breaking a sweat. Emacs 23 is
unable and every now and then resorts to recentering (which I hate).
Thanks to hard work by Chong, it now happens only occasionally,
instead of once every two or three screenfuls; I just witnessed it
five or six times scrolling up to line 2,000 of lisp/ChangeLog.
Fortunately, it's not every day that I scroll hundreds of lines
line-by-line, so it is bearable. But there's no doubt there is a
performance regression with respect to Emacs 22
