Freebsd IP Forwarding performance (question, and some info) [7-stable, current, em, smp]

[Paul]

Yes it does but it seems to use a lot more of one cpu than the others so 
It's really not SMP.. Can I stop it from doing this with some setting?
Why can't there be 4 taskq's?

Also with full internet table I can't even do 100kpps without errors.. I 
don't get it :/  I could do 300kpps on a p3 and now I have a 3ghz xeon 
and 2.2ghz opteron  brand new hardware and can barely get more than 
that.. Doesn't make sense to me.
