Gbps practical performance?

Hi 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

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 machines.

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.
