CSMA/CD, along with the required headers and inter-packet-gap limits it a little, but it should be a lot more than 60Mb/s. The ability of a host to get data into and out of the NIC, in addition to disk drive speed and such, is much more significant for gigabit on current…
Read the full replyHi all,
From what I know, the the nature of CSMA/CD limits the practical
performance on a ethernet network. If I remember right I have once learned that about 60 Mbps is what's possible to expect in reality from a 100 Mbps ethernet network.
What would the corresponding figure be for a Gbps ethernet network?
Thanks,
Anders

Horsefeathers. I could consistently get 80+ Mbit/s on 100BaseT 90+ even. The only catch was capture effect in half-duplex. And there is no CSMA/CD or capture effect in full-duplex.
Well, given that gigabit "always" runs full-duplex, what someone else said about the CPU horsepower and what sort of data (source/sink) one is trying to push over the net.
