But also the the analysis and reporting of the results by Phoronix is simply moronic to the point of being worse than useful, they are spreading misinformation. Take the first test as an example, Blogbench read. This doesn't raise any red flags, right? At least not until you realize that Blogbench isn't a read test, it's a read/write test. So what they have done here is run a read/write test and then thrown away the write results for both platforms and reported only the read results. If you dig down into the actual results, http://openbenchmarking.org/result/1112113-AR-ORACLELIN37 -- you will see two Blogbench numbers, one for read and another for write. These were both taken from the same Blogbench run, so FreeBSD optimizes writes over reads, that's probably a good thing for your data but a bad thing when someone totally misrepresents benchmark results. Other benchmarks in the Phoronix suite and their representations are similarly flawed, _ALL_ of these results should be ignored and no time should be wasted by any FreeBSD committer further evaluating this garbage. (Yes, I have been down this rabbit hole). Best, SamReceived on Thu Dec 15 2011 - 11:56:03 UTC
