Nice slow performance can also be achieved by forcing one end of a
perfectly good cable to 100meg/Full, and telling the other end to
negotiate. [Hint...the standards require the negotiating end to use half
duplex upon negotiation failure.]
It took us longer than it should have to understand the "late collision"
counts on the poorly-performing segment. We try not to do that any more.
