Two interesting articles on AnandTech about performance comparisons. I am not so interested in what the actually found, but I am very interested in the way the went about trying to find the causes of the performance differences.It depicts a very common process for performance testers. From the site:A little bit more than a month ago, AnandTech published "No more mysteries: Apple's G5 versus x86, Mac OS X versus Linux" with the ambitious goal of finding out how the Apple platform compares, performance-wise, to the x86 PC platform. The objective was to find out how much faster or slower the Apple machines were compared to their PC alternatives in a variety of server and workstation applications. Now they have followed up with part 2.
