I tested copybreak long time ago and saw no gain from it. Do you have pointer to the patch? > It seems the route cache may/should be tuned, but I dont know how. 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. --ro
