This helped me with my slow scroll issues.  Holding down arrow on a fully
maximized frame on a 1080p monitor was spiking my duo-core CPU to 20-25%.
Scrolling text.  50% of one CPU.  Just to scroll text.  And it would start
jumping around almost right away.  With this setting, it goes down to 8-14%
while scrolling.  Still kind of silly, but that's better than emacs23.

Do you have any other useful emacs24 settings?
