RE: Maximum traffic on Gigabit Ethernet

I am interested in this discussion as well. I have heard some engineers state
that Cisco has a limit of 750Mbps on their GigE interface on any router or L3
Switch, but I have seen throughput of up to almost 1Gbps on a layer2
interface, with any size packet, and a throughput of around 750Mbps with
90-100 byte packet flood, on SVI and Layer3/routed ports, mainly because of
the queue length/buffer of 75 packets on the interface. Never tried increasing
the queue length and testing the routed or SVI interface throughput with small
packets but would be eager to know if someone has done a more thorough
testing!
Thanks,Muhammad
