Earlier this week Phoronix published a set of comparative benchmarks regarding Ubuntu, testing various recent releases to compare their performance figures on all sorts of different tasks. They've now done the same thing for Fedora, so we can compare Fedora and Ubuntu in terms of performance.

I think the Linux kernel and the method Ubuntu and other distributions use to compile it has a big role in the gradual degrade of performance.
My guess is distribution kernels select nearly all the options in Linux's makeconfig utility to provide common denominator support for most generic hardware and select basic performance optimizations for a broad-range of x86-based CPUs.
The situation will only worsen with time; therefore performance conscience users may consider re-compiling the kernel with only the necessary drivers and specific optimizations for their CPU type.
