I'm confused... didn't ubuntu x86_64 win most of the tests?
Why the dissappointment with the ubuntu results, that some of the posts here express?
The Nexuiz tests on intel graphics are not interesting to me.
sqlite test is important. Most sane people would use noatime or relatime, which should have dramatic results.
I would love to see someone with similar/identical hardware post some PTS global links with different configurations/distros for comparison. Also, GNU/Linux is as much about choice as anything else - having the most default setup beat osx is just an added bonus.
