Jasjeet Sekhon benchmarked Linux and MacOS X on the MacBook Pro using his statistical software, and finds that "Linux is found to be much faster than Apple's OS X for statistical computing. For example, in one benchmark Linux is more than twice as fast." Earlier, he ran tests on a G5 and an Opteron, and conlcuded: "Those results were terrible for OS X and not particularly good for the G5 (970) chip. For example, my 2.7 pound Pentium-M Linux laptop is faster than my 44 pound G5 running OS X. The floating point performance of the 970 chip leaves much to be desired, but OS X makes the performance problem significantly worse."
