I'm sure Peter isn't the only one who > might be interested in this kind of information! Yep, good idea. Nevertheless, I'd like to see a "standardized" measurement process plus nice latency plots, like this one: http://www.pengutronix.de/oselas/realtime/results/20070211-1/phyCORE-MPC5200B-tiny-20070211-1.png to have a good comparism base. These plots are basically be done without a sane realtime workload (well, some while true; do find /; done loops, plus ping -f, but that can probably be done better). Any idea for a good realtime workload scenario which is valid to all supported platforms? Robert -- Dipl.-Ing.
