Alex and I rewired our entire network the other day with cat 6 cable and new gigabit switches. Once we got it all set up we decided to do some testing. One of the tests we ran was transfer speeds from our file server to our laptops. We were trying to determine the network linkspeed when all of a sudden I realized that I had no idea how to do this on my mac.
