Hi lists, Are there any profiling tools in the system or ports that would allow me to determine how much processing is being done per packet and how long does it take? I would like to predict possible PPS load for my system and perhaps locate and remove some bottlenecks. Is IPFW efficient enough to firewall 2x10GE (in+out) interfaces without much latency increase, when running on modern hardware with Intel NICs? Majority of processing tasks would probably be setfib according to matches in tables. Pawel.
