I was referring to the router with 4 switch ports. That's often 
sufficient for people. We're talking about two different things, 
apparently. :)

According to the network guys at the colo facility, this is something 
they've seen with all unmanaged switches.

1. Cost.

2. The servers never saturate the 100Mb/s connection.

3. I wanted the switch mostly to accommodate the out-of-band remote 
access cards. I don't really care if that interface is slow but if it 
slows down the main interface to 10Mb/s half-duplex, that's a problem.
