no, wrong.
The MacOS kernel is "related distantly" to the FreeBSD kernel.
It has been derived from MACH 3 and MACH 2.5 which themselves had SOME
components
derived from BSD4.3. Some of these components have been updated to the
equivalent
companents from modern BSD systems and BSD4.4 in turn borrowed the VM system
from MACH. So, they are related but not in a parent/child manner. MacOS
has been designed
and evolved with a very different set of goals from FreeBSD, so many
different tradeoffs
have been made along the way. They have very different behaviour
characteristics.
It would like to understand because the performance of a MacOS as serving
it is very inferior of what a FreeBSD server, being that the MacOS is
derived
from kernel of the FreeBSD.
It will be that somebody could explain this better to me.
Thanks,
