Default Re: Nvidia GTX 260 performance decrease more by a factor of 2 Debian vs Sabayon Linux

What happens if you install the older GCC that debian is using, and use it to compile a 2.6.30 kernel to downgrade to?

That way they would both have roughly the same kernel compiled with the same version of GCC.

I also notice they are also using different filesystems, but that shouldn't matter.

EDIT: Does phoronix test suite compile stuff before testing? If so, the benchmark application itself would be effected by the version of GCC it used.

EDIT #2: And kernel config options like Preemption model or Timer frequency might make a difference too.
