 With top I can see very high interrupt cpu states, when forwarding high
 packet rates.

Is there much difference if you switch to GENERIC instead of GENERIC.MP?
(probably installed as /bsd.sp; you can either rename the file, or type
'boot bsd.sp' at the boot prompt, or 'echo set image bsd.sp  /etc/boot.conf')

I cant see much difference running GENERIC. Maybe a little bit more
throughput, but still with the cpu on fire.
