Freecale says that the ethernet interface has a 400Mbit/s memory interface, so that's pretty much the physical limit and I think even in summary of both directions. The hardware also has some very fancy IP offloading stuff, of which I don't know how much we already utilize. As an interest off myself, when you already have such a setup running. Can you do a ping test to see what latency you get during bulk traffic and without? Currently I can't easily do such tests myself, since I have a full workbench with unrelated stuff. -- B.Walter http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
