I was referring to the relative ability of each chip to keep the cable
occupied with useful data over the long term. OBVIOUSLY both chips have
to be able to operate at an instantaneous rate of 10 mb/s.

Van's results were of the form "it took X seconds to transfer a
block of Y bytes over Ethernet using TCP/IP."

I would rather let his results speak for themselves.
