I can't point this out between Linux and FreeBSD, but back a few 
years ago, when I was involved in benchmarking high performance
systems for purchase here, we found this to often be the case.
Some systems just screamed on certain very parallel tasks, but
practically came to a halt when a mix of tasks were run or even
when trying to edit a script while things were running.   Others
were slightly less hot on the highly specialized tasks, but did
well - much better - on the mix.  We chose the system that handled
the mix - which ran a BSD UNIX by the way, although a proprietary
version as did most back then.

Anyway, so, even though I haven't compared FreeBSD and Linux, I am
not surprised to hear someone say there is this sort of difference.
It is possible.   Someone might investigate further and put out
some verifiable numbers.
