You look at network file system issues and generalize that to generic networking. I am sorry but I do not think you know a whole lot about high speed networking. You forget that when talking about fast networking it depends on what you define as fast. Some people consider file serving performance others are interested in fast memory to memory transfers (from data aquisition servers to client processing units for instance). For bulk data transfers on high speed networks (note I do not consider 100Mbit/sec Fast Ethernet as being a fast network) the real here issue is pipelining through socket buffers and large TCP windows and not latency.
Besides, the fact that there are 90M netware boxes around doesn't matter when most of them are running IPX - IPX is braindamage and has nothing to do with proper networking.

I'd love to see a netware box sustain 110MB/sec (MB as in mega byte) memory to memory in two TCP streams between dual 400MHz P2 boxes.
