8.0-CURRENT: having pf enabled without any rules impacts forwarding performance

[Deomid Ryabkov]

i have a machine with nc running through it.
with pf disabled, i see 960-970 mbit/s through it (as reported by systat 
-ifstat).
just having pf enabled, with empty ruleset:

# pfctl -vs nat
# pfctl -vs rules
#

reduces throughput to about 700 mbit.
this seems wrong. any ideas why this might be happening?

thanks.
