For a while I've noticed that scrolling has been pretty slow, a couple of months back it improved quite a bit.  But still, noticably slow.

I decided to elp-instrument some likely candidates:
In a recent version of emacs, built a few weeks ago from cvs trunk:

smooth-scroll-lines-from-window-bottom  943         18.337000000  0.0194453870


From a version built a long while back, GNU Emacs 23.0.50.1 (i386-mingw-nt5.1.2600) of 2007-10-23 on myhost:

Both of those elp-results came from pressing C-n on the same file from top to bottom.  The file has 671 lines in it.  It appears to me that the more recent versions of emacs have very slow "next-line"

At least bug#1611 compares Emacs from before the introduction of line-move-visual and after it. That variable is non-nil by default, and movement by visual lines is definitely slower than moving by physical lines. It's still reasonably fast IME, but if people want the pre-Emacs-23.1 behavior, they can customize line-move-visual to nil.
