well this i cannot really say because it uses ipfw for filtering
(although i have implemented a jump optimization in the ipfw rule
scanning which lets you arrange rules in a tree with cost proportional
to the length of the actual search path as opposed to the original ipfw
which had to scan the whole list.

not at all. it runs completely in the kernel.
