In fact this type of result is not surprising at all, it has already been
found by mysql specialists benchmarking Linux and FreeBSD here:
Of course one needs to look the results *after* the sentence:

I'm not big expert in FreeBSD and did not saw before. This page recommends to use libthr
instead of libthreads.
 The results with libthr looks better:
which show that, on a dual core athlon, Linux and FreeBSD are basically
equivalent. The real FreeBSD problem is that people say that it does not scale
well on more than 4 processors. But, obviously things are becoming better and
better, and machines with many processors are still not very common.
It has taken a lot of time until Solaris has been optimized to not be a mollasse,
and similarly Linux has taken some time before scaling well.
