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? -- Le --20cf300fad7932aeca04ad9e27a6 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable

If so, I have no idea whether this will help or help you find the problem, = but
you might try doing this to see if it makes a difference:

(setq-default bidi-display-reordering =A0nil)

This helped me with my slow scroll issues.=A0 Holding down arrow= on a fully maximized frame on a 1080p monitor was spiking my duo-core CPU = to 20-25%.=A0 Scrolling text.=A0 50% of one CPU.=A0 Just to scroll text.=A0= And it would start jumping around almost right away.=A0 With this setting,= it goes down to 8-14% while scrolling.=A0 Still kind of silly, but that= 9;s better than emacs23.

Do you have any other useful emacs24 settings?
