After upgrading to maverick I have noticed this problem. While update-manager is in the "Building Data Structures" state, Xorg CPU usage is 80%+ on my Core2Quad6600. There are other situations in which Xorg consumes an unusually high amount of CPU time. Examples:
- Frequently adding lines of text in gnome-terminal (eg. output while running apt-get upgrade)
- Scrolling pages in firefox
- Scrolling text in Eclipse

It appears that xorg is inefficiently repainting large areas of the screen, and update-manager is one was to reliably reproduce this issue.

Video card is nvidia GeForce GTS 8600 running current nvidea proprietary driver.

Is there any diagnostic information I can provide?
