I do not think is a lot of time to install Sabayon a run the Phoronix suite - about half to 1 hour, if you use unetbootin or Multisystem - and Gentoo is, to have a 1000 Hz kernel running game tests.
Of course there are no PPA with a Ubuntu 1000 Hz kernel to test it fast.
It would be a great idea, I suggested it to Lorenzo Carbonell, el atareao, that does some pretty staff for ubuntu as contact lens, freecache, or google reader indicator. I hope he or any other one else would make a 1000 Hz kernel for ubuntu at his PPA.
But making a 1000 Hz Ubuntu kernel and add it to the benchmark is also a less than 30 minutes - 1 hour procedure, and you will have it done for future benchmarking - or at least a script to do it faster and easily-.
And of course, if you let Gentoo compiing, while you do other things, or all night it would be a great test.
The gentoo compiling time is a great indicator of how fast is a computer.
But Sabayon is a great aproach for desktop users, unfortunately there are no a PPA system for it, perhaps PPA developers should add arch, sabayon, debian and rpm packages letting the users to choose the distro.
And distros agreee to use a similar names for packages with different "surnames" or extensions, But that is other issue.
I want fair benchmarks and linux kernel for gaming compiled at 1000 Hz is far better, Ubuntu choose to compile the kernel at 100 Hz, gaming benchmark is unfair for Linux vs MS WOS if there are no other kernels compiled at 1000 Hz at the charts.
