with Jumbo frames on standard commodity hardware between two standard
440BX based PCs.

I have bad news for you Jeff. Thats not a NUMA fabric. Thats GigE. Thats what
people plug larger than office sized servers into nowdays. Current NUMA fabrics
are a good factor of 10 faster still.

At what. IPX - sure. How about at telnet serving.

The equivalent to the netware specialist fast paths for file serving is Tux,
and Tux currently holds a world record. I'd love to see Manos beat Linux +
Tux at specweb. That would vindicate your arguments
