Do you have a managed switch behind a router in system? Maybe a 1G Hz router feeding a 100K Hz router? Most newer boxes have a 1GHz NIC (built in) in them. We have a managed 1 G Hz switch that is managed and we have a Motorola router that is less than 1 GHz with factory default set up. The switch shows up on our network as a device! I sort of wondered about it as a cause of our stack up (slowness) sometimes in the afternoon. I have never seen much discussion about a managed switch and network performance.
