It hasn't convinced me. I am convinced that implementing a user-mode
NFS on Pentium-class machines is going to be fine on a 10 Mbps
network, but I didn't need this discussion to convince me of that.

The reason I specified 486-class machines (aside from the fact that
I own only 486-class machines :-)) for the NFS tests is that a
high-end Pentium-Pro-class machine is about 4-6 times faster than
a mid-range 496-class machine. Therefore, if a mid-range-486-class
machine cannot do well on a 10 Mbps Ethernet, we can hardly expect
better utilisation out of a Pentium-Pro-class machine on a 100 MBps
Ethernet or 155 MBps ATM circuit.
