I have a setup at home in which I am going to have a firewall between my cable modem and my pc's and xbox. To do this I have a 5 port switch - so everything is plugged into the switch, and then the firewall lan is plugged into the switch, and the firewall wan is plugged into the cable modem
I had some problems with lag so I have thought I would troubleshoot by having the pc's and xbox plugged into the switch, and the switch is now plugged directly into the cable modem. So on one port on the switch, I have a network cable connecting my cable modem to my switch, and then the pc's and xbox are plugged into the switch. This works fine, but all of my network traffic is going through one port on the switch and through one network cable.
so I started wondering, couldn't that potentially be a bottleneck? I don't noticed any lag with this setup, but can't help but wonder if there is a better configuration? For example, are there switches that have a port for this type of setup so the port that is handling all the traffic is faster than a normal port. Or if, for example, all the ports are connected in a special ways to distribute the network traffic more efficiently when all traffic is originating from one port?
