Situation with bi-directional traffic is better (not sure how much). I'm 
intentionally not testing this case to discover rough cases (like 
contested interface counters) faster.

Here is statistics from one of the machines running in production
* E5645
* Intel 82599
* HT turned on (so 16 out of 24 cores are used)
* Modified Intel drivers
* 8.3-S kernel with interface rlock patch
* ipfw counters eliminated
* global forwarding counters not eliminated (-another 100-200 kpps)
* route locking eliminated (modified version of original patch in the 
first message)
* 8 vlans
* IPv4 traffic
* 4-8 firewall rules to pass
