changes to sysctls are not persistant. of course, you could program
something to record the value on shutdown and restore on boot.  that'd
be overkill, look at the firewall_* directives for rc.conf.

regardless, packets will not go very far into the firewall code if no
rules are present. i would seriously doubt you could observe any
performance difference.
