I've yet to see phoronix perform a benchmark test where they actually used the same rig to perform benchmark comparisons. Too many things change from one benchmark to the next to be able to reliably say what is at fault for the benchmark differences. The test needs to be re-ran in an environment where the only thing that changes, is the operating system. These benchmarks only show that linux on one machine performs differently than bsd on an entirely different machine.
