I have some pcs where I have had to install two nics, one nic dedicated to Windows 7, one nic dedicated to xpmode. Performance is very good.
The internal card is a Realtek. The external (pci1x express card) nics is an Intel Desktop Card.
I connect both cards to a Netgear 5 port gigabit switch and then connect the gigabit switch to the main switch in the closet. I have everything set to NOT auto negotiation. I have to use a small switch since each office only has one ethernet port.
What I am concerned with is how much traffic am I adding to the network or am I adding any additional traffic to the network. My network flooded recently and was not sure what the problem was even though I had a monitor on it.
Is connecting a small switch to a larger switch inefficient?
