Phoronix: Ubuntu 10.10 vs. Mac OS X 10.6.5: A Competitive Race

Back in May, we published benchmarks of Mac OS X 10.6.3 vs. Windows 7 vs. Ubuntu 10.04, along with other times, looking at the performance of Apple's Mac OS X operating system relative to Ubuntu and other Linux distributions. In most of those articles though we used Mac Mini computers, but now with a new Mac Book Pro in our labs with the latest Apple/Intel hardware, along with the most recent versions of each operating system, we have carried out a new set of tests that is also more in-depth than our earlier published benchmarks.
