"For this testing we had compared the stock packages
found in Ubuntu 8.10 x86 to that of what's committed already for
the Ubuntu 9.04 x86 development branch as of December 18, 2008. We
had done a fresh install with each package set and used the
Phoronix Test Suite to facilitate our Linux testing. Ubuntu 8.10
uses the Linux 2.6.27 kernel, X Server 1.5.2, xf86-video-intel
2.4.1, and Mesa 7.2. The Ubuntu 9.04 packages we were using
included the Linux 2.6.28 kernel, X Server 1.5.99.3,
xf86-video-intel 2.5.1, and a Mesa 7.3 snapshot. The stock packages
and stock settings were tested in each configuration. In this
article we were simply looking at the stock Ubuntu performance.
"The Intel IGP we were using for testing was a GM965 Chipset
found on a Dell Inspiron 1525 notebook. This notebook also
contained an Intel Core 2 Duo T5800 at 2.00GHz, 3GB of DDR2 memory,
250GB Hitachi HTS543225L9A300, and the LCD panel operating at 1280
x 800"
