The problem with FDDI is relatively high cost and latency. The way to get more throughput from fast Ethernet is to use a switch. I have all of my machines on a 24-port switch and I run full-duplex 100 Mbps Ethernet which means no collisions and no backoffs. So I get the whole thing except for overhead from packet framing and all that.
