Is that sending 1 byte of data per packet, or batching up several/many bytes per packet? (and mostly measuring the CPU time for a one byte send/recv pair) Even if you have a test program that blasts lots of packets, that won't mimmic real traffic. It's bypassing all the setup of ARP and router slots. The only really useful data I've seen is the numbers from the people running heavily loaded servers. -- These are my opinions, not necessarily my employer's.
