Which is to say, just the sort of application for which OS differences are unlikely to matter much. (Compared with, say, what compiler happened to be used to build the application, or what else was running on the mcahine at the same time.)

Unfortunately, many of the benchmarks they used seem to be of this sort. Not that it matters much, since the author of the article offered basically no analysis or explanation of any of the results, just a series of barcharts, each followed by a single paragraph trying to find a superficially different way of paraphrasing the numbers in the barchart.
