    Looks about right (I don't optimize things that much in all cases,
but I've come close before). Here's a PR I opened that would tune the
rc.d scripts, because you'll probably notice that there's a ton of
noise involved at bootup when you do the above items:

http://www.freebsd.org/cgi/query-pr.cgi?pr=conf/145344

    If desired, I can update the patch with latest HEAD for the PR. I
would need for someone to review the item though and help commit it.
Thanks!
