My test setup was the same in both cases. I connect to the RTAI/Xenomai PC via telnet and let the latency test run for about 5 minutes. No other activity happens (well, there are a couple of services running like apache, ... - but they should not cause any load). The strange thing, is that in Xenomai even after a few seconds a latency in the range of the maximum latency is shown. I can retry the tests using a background stress situation. -- Mathias Koehrer [EMAIL PROTECTED] Viel oder wenig? Schnell oder langsam?
