One datapoint which may be of interest: I have (repeatedly, consistently) been able to get 75-80 Mbit/s between two P133s with SMC Etherpower 10/100 cards (100BaseTX) connected back to back with a TP crossover cable. Tests performed with both netperf and ttcp give essentially the same results. You can view my netperf results in the netperf database at http://www.cup.hp.com/netperf/numbers/NetperfBrowse.html look for FastEthernet network type. It should (at least in principle) be possible to do better with FDDI, due to higher MTU. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
