Warning: This is likely a stupid question.
My wife and I play World of Warcraft simultaneously at home on a DSL network. My Intel-based computer as well as my wife's Mac natively support Gigabit Ethernet. Our Linksys router is not Gigabit Ethernet compliant. I am trying to decide whether or not to upgrade to a Giagabit Ethernet switch/router.
1.) I need an expert to clarify any misconception(s) I have about the speed advantage of switches in general prior to discussing Gigabit Ethernet specifically. Recently, I did some research about TCP/IP (which makes me dangerous enough to think I know what I'm talking about) and I want an expert to verify or dispute my deductions. Switches operate faster than routers - due to the fact that switches simply read the IP header and "route" the traffic "at full bandwidth" to the proper port. Whereas, routers need software to decypher the TCP header and are forced to "shotgun broadcast" to all downstream ports causing "packet collisions." I think I read a statistic that theoretically an ideal router can operate at a maximum effecientcy of 60% or something due to the "shotgun approach." Thus switches are far more effecient.
2.) I know that a valid purpose of installing Gigabit Ethernet in a home networking situations is to allow the internal sharing of data at Gigabit Ethernet speeds. However, I'm a hardhead. I want to believe that a Gigabit Ethernet switch will enhance my World of Warcraft performance due to reduced "packet collisions" if nothing else. Am I dreaming?
Thanks for the time you put into tactfully telling me that I'm dreaming.
