If you used iperf, you applied it on the non-rt channel of RTnet with RTmac or rtnetproxy, right? Is that what you actually want to measure? Or are you interested in the rt bandwidth? In the latter case, writing a real-time application is required for the measuring. Maybe you can adopt the iperf code to run via the Xenomai POSIX skin against RTnet, never checked. In any case, numbers regarding bandwidth won't be impressive as RTnet is after deterministic latency. Jan
