Half duplex Ethernet slows down when there are collisions, but there
is no wait to transmit whenever the link is idle.   With FDDI, there
is (you wait for the token).   So at high load, half duplex Ethernet
might be a little slower than FDDI, but at modest load, it will
definitely be faster (lower latency).

But, doesn't the GIGAswitch get around that by generating a token for each port?   Isn't that how switched-FDDI works?
