For example, you run a test on a P6-200 with Linux and P5-133 with FreeBSD. Because the Linux runs are faster than FreeBSD, does NOT MEAN that the Linux kernel is better (faster) than the FreeBSD kernel. All you can say is that the faster machine ran the BENCHMARKS on Linux faster than the slower machine ran the BENCHMARKS on FreeBSD. My position is that BENCHMARKS are good ONLY at measuring what they measure, and to compare OSes, it is very important to understand what is measured. Since most people don't understand what is being mesasured, because they most likely don't read the code, the conclusions made by people who analyse the results are as influential as the benchmark numbers themselves. Just be careful and have integrity with conclusions. John
