That depends directly on the amount of screen updates taking place.  If
you're viewing a Web page with a lot of animated PNG's or GIF's, then
more traffic will be used.  If you run TuxType, you're staring at
73Mb/sec (I measured this a few years ago), so you really need a 100Mbps
Full Duplex link in that case.  On the other hand, if you're just doing
simple, basic word processing or Web surfing to something like
www.gnu.org, then 10Mbps Half Duplex is liveable.
