logs
Kernel is only changed component between tests.
Gtkperf results droped from 1.16 sec to 1.83.
I've attached dmesg, Xorg, and gtkperf log - so you can see which tests
regressed more.
<a href="http://ie.microsoft.com/testdrive/Performance/ParticleAcceleration/">http://ie.microsoft.com/testdrive/Performance/ParticleAcceleration/</a> test in
Mozilla Nightly also regressed noticeably. but don't remember exact number.
I don't have any 3d benchmark suites. But brief look at World of Warcraft
(direct3d over wine) 3d performance didn't show much difference.
All test was done with 08e71e1820d6fcb6829b4ebd360beadc1f250295 git revision.</pre>
