 Does the copybreak help? I tested copybreak long time ago and saw no gain
 from it. Do you have pointer to the patch?

 Tuning is not an easy task and not necessarily you will gain anything,
 It fully depends on your input traffic but it seems your system has a 
 lot of dst entries. Which would cause a lot linear search. Packets per 
 flow and no of parallel flows should be of interest for you. rtstat can 
 give you a better feeling of incoming routing load.
 
 Is 10kpkts/s the max performance?

 Cheers.
