Depending on the details of how they did the benchmarks and how they processed the results (if at all), the results can even be within the margin of error (i.e. useless for mutual comparison except to show the systems are all very similar). The benchmarks they did are mostly focused on number crunching and do not even touch the area of system scalability to multiple CPUs, which could have been easily done but they chose not to. Number crunching is a bad choice for system scalability measure because down to the metal, all systems use similar compilers and there's nothing the OS can do to improve (or actually hinder, in the common case) CPU's execution of math code. For example, they could have included the "shells concurrent" benchmark from unixbench, started multiple bonnie++'s in parallel, and included a few system benchmarks like lighttpd+siege, parallel gzip (pigz) and blogbench. > "However, it's important to reiterate that all three operating systems > were left in their stock configurations and that no additional tweaking= > had occurred." >=20 > I kernel debugging stuff still enabled in FreeBSD 7.1 BETA 2, if so > these results are useless > and someone should contact the article writers to correct this. There is no debugging in -STABLE.
