Comment 119 for bug 38131

The gnome-settings-daemon problem is not the main issue at stake here as it doesn't fix the problem for me.

The main problem here is not one that only affects older computers. When searching for something which returns a lot of results on launchpad (like, ironically, "Xorg CPU") my firefox slows down to an unusable state and Xorg uses 100% of one processor core. This is on a 3.86 GHz core 2 quad with 4GiB of DDR2 942! If that system can't run a single tab in firefox then there is a SERIOUS bug here!

There is a possibility that this is made worse by my peculiar X setup, using two Nvidia GPUs with the proprietary driver with four monitors and Xinerama.
