Subject:   ipfw dst me usage performance noticeable?

ipfw(8) says:

"Specifying me makes the rule match any IP number configured on an
interface in the system.  This is a computationally semi-expen-
sive check which should be used with care."

Does using 'me' in the last few rules (just before the deny all) that
match TCP setup packets etc make sense? (I.e. is the performance loss
for this kind of usage something one would notice?)

(The bulk load of packets should be taken care of the rule above that
passes through all already established traffic..)

Regards, Markus.
