all must be 1gb to have true 1gb netwk speed

A friend I had once told me something that I figure was true but I'd like to get a confirmation on.

He said in order to get true 1gb networks speeds all systems connected to the switch must be running at the same speed. That is to say any computer running 10/100 will compromise the 1gb speeds.

Is that true?

my setup. I have an unmanaged netgear switch that everything plugs in to. It does auto everything.. I dont even have to worry about up links ( not saying this is a good thing, but just saying). All of my computers are now on 1gb full speeds. but my cable modem is on a 10, and my wireless router is a 10. I have 4 grouped ports of 8 jacks on the switch. I put all computers in the first 3 sets of 8 and the router and wireless hub on the other( not sure that even matters )

No that is not true. Your friend needs to review some of the data sheets concerning gig switches for a better understanding.

You'd have to have him get you a very exact set of conditions. It might be that he could propose a situation that it might seem true. It is true that you can't get the 10/100 to talk to a 1G at 1G speeds so in a round about way it might be true.

Also some old routers do report wrong. The old router could actually take packets away from faster routers but there aren't too many of them out there.

As for your install, there sometimes is a special port that may be usable to stack switches. Most times any port is fine. If one goes bad another usually works fine. We don't usually replace them for one bad slot.

I am not a bit fan of 1G unless you have some very high end servers. Just don't think there is much true value to anything above 100M speeds on a home computer. Too much chatter taking up processor time.

Set all to 1G and run perfmon on processor then set all to 100M and see if any reduction of processor.

In all not much difference. You can't download faster than your modem

The question was about the entire switch stepping down to the slowest port speed which is something switches don't do.
