I suppose 40 nanoseconds is feasible. The NDTL web server at Harvard university has latency results from any vendor that participates in their test. They have measured 4-8 microsecond latency for one of the Gigabit Ethernet companies which seems pretty good to me. The good thing about the NDTL is they perform the same set of tests for all vendors. Vendors can choose to prevent the results from being made public, but that is really the only flexibility. To me, this is a level playing field. The best performance sites for GE NICs are the leading vendors -- who want to demonstrate that GE NICs are fast enough to buy. These are: www.alteon.com www.packetengines.com and Essential Communications (I dont have the link) For Vendors that are shipping Gigabit today (only 3 that I know of) switch perfomance must be measured using a Smartbits. I personally tested an 8-port GE switch that was able to forward 11.9 million packets per second (8 streams full duplex) at layer 2 and layer 3 -- pretty impressive.
