I just got a MacPro at work and I will use this machine in conjunction with my Powerbook a lot. I realized that I could connect the Powerbook to the MacPro with an ethernet cable, given that the MacPro has two ethernet ports. I turned on internet sharing and I am able to browse from the Powerbook and connect to the MacPro as a server. I expected near Gigabit connection speeds when transfering files between machines, but the were closer to 100Mb (~7-9MB/s). Is it possible to connect the two machines and get Gigabit speeds?
