Xorg with XAA acceleration method in Jaunty is still slower than in Hardy. I tested two very simple benchmarks:

Open a Gnome Terminal, and run "top".

1. Moving window: Move the Gnome Terminal window, and watch the CPU usage of the Xorg process.
2. Test scrolling: Open another Gnome Terminal, and type the following command:
   $ while : ; do dmesg; done

In both cases, Xorg consumes about 50% of CPU cycles in Jaunty, and 25% in Hardy.
