The Gauntlet packet filter code stores the rule data in a form that is
trivially searchable with ordering that's designed to quickly skip rules
that don't apply. However, the list is linearly searched - rule bases of
less than several hundred rules on an Ultra SPARC should be no problem for
performance.
Your mileage may vary - measurement is your friend ;-)
