[SOLVED] CPU use ~25% in X while Typing (xterm, firefox, etc.)

Hello --

While typing continously, X usage gets up to 25-35% -- high enough to notice a sluggishness on the keys and make things  unpleasant. It's not usually a problem -- but when writing something fast, it's intolerable. Anyone know how to troubleshoot such things? Do people get comparable CPU usage on comparable machines?

$> uname -a
Linux sl-laptop 2.6.35-ARCH #1 SMP PREEMPT Wed Sep 29 07:17:20 UTC 2010 i686 Intel(R) Core(TM)2 Duo CPU P8400 @ 2.26GHz GenuineIntel GNU/Linux
$> X -version
X.Org X Server 1.9.0
Release Date: 2010-08-20
X Protocol Version 11, Revision 0
Build Operating System: Linux 2.6.34-ARCH i686 
$> lspci
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

I'm running DWM, but I've had to same problem under Awesome (worse, perhaps). No problem outside of X.

**EDIT SOLVED**

For anyone else who has this problem, cairo no longer comes with xcb support -- for one reason or other, I had updated my cairo-xcb to the latest cairo, which taxed X like crazy. Replacing cairo with cairo-xcb did the trick. Now things work nicely.
