The first thing I did was to run the latency test in the the xenomai's test= suite directory. The results of the worst time latency are really ugly - about 40=B5s! On the very same PC I got a value of about 5=B5s using RTAI 3.3-cv running = the RTAI's user/latency test. My question is now: Why can there be such a huge difference between the two= systems on the very same hardware?? Is there a way to improve this value? The RTAI system uses a 2.4.33 kernel, the XENOMAI uses the 2.6.17.7 kernel.= Could this be an issue? Thanks for any feedback on that issue!
