I believe there is = usually a hardware bottleneck between the SoC and the Ethernet complex = that is significantly narrower than the Ethernet ports and switch = fabric.

Pete = Heist has established that it can sustain 600Mbit through Cake without = much CPU load or added latency. Above that level the characteristics do = degrade a bit. - Jonathan Morton
