is relatively new. My guess is that if there is a problem it's ZFS
specific. If it were a more general problem I think we'd see a lot more
complaints, whereas ZFS already has a reputation for needing lots of
memory.
you may precisely set up a limits of memory that ZFS would use at most. or
just
If you really are having a problem with FreeBSD you are going to have to do
a lot better than this in terms of providing some data points which define
the problem. I am in agreement with Adam here: either you can work the
problem or you can troll. I don't see any indication yet of any real problem
"2) Inactive memory (which is memory that has been recently used but is no
longer) is supposed to be seamlessly reclaimed automatically by the OS when
needed for new programs. In practice, I?ve found that this isn?t the case, and
my system slows to a crawl and starts paging out to disk when free

The simple answer is no. A more complex answer:
% grep -ri fr
does OS X kernel share any code with FreeBSD kernel's memory management
subsystem ?
IMHO no. OSX is somehow-microkernel based, they did take things from
FreeBSD but not this IMHO.
anyway - who cares
Something is deeply broken in OS X memory management

The simple answer is no. A more complex answer:
% grep -ri freebsd xnu-1699.24.23 | wc -l
520
% grep -ril freebsd xnu-1699.24.23 | sort | uniq
% grep -ril freebs
