Paul - Phoronix has a history of "performance benchmarks" that skew *heavily* towards Linux and away from the BSDs, which is to say their "benchmarks" are hardly indicative of Real Life. I know I'm in for a laugh any time I see someone reference one of their "performance tests" regarding Linux/BSD. Sadly, a lot of folks will look at that and say, "See? An independent, non-biased review..." kmw
