The results seem well within expectations, for the sort of benchmarks
they did: there is little difference between the systems. 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

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

There is no debugging in -STABLE. WYSIWYG :)
