I don't understand why your off-machine RCP performance is so poor; you do decently with on machine RPC (relative to other RPC implementations like that at DECSRC), but your off machine (over the net) case is only comparable to what a MicroVAX running Topaz can do, or just running over TCP (X round trip times on Ultrix over the net using TCP are less than a factor of two worse (around 3.6 ms)).
