But switches have no sense in a 1 server environment because all of the trafic goes and comes from one point. Unless your clients are 100Mb and the uplink to the server is 1Gb. People often believe switches will improve their network speed, but that is not always the case. But indeed the prices of the switches have dropped that you buy a switch at the price of a good hub these days.
