> BTW, have you disabled CPU frequency scaling (CPU throttling) BIOS/Linux config? No, I did not but built with disabled CPU frequency scaling does same. Following is the result after overnight test with no load but default services running. RTH| lat min| ovl min| lat avg| lat max| ovl max| overruns RTD| 1304| 0| 1815| 3118| 43940| 7 RTD| 974| 0| 1823| 3900| 43940| 7 If I stop and start 'run' then overruns changes but the number does not change over time, it seems that is somehow locked. Following is the output with intense load (disabled CPU frequency scaling), again overrun number don't change from start. RTH| lat min| ovl min| lat avg| lat max| ovl max| overruns RTD| 267| 0| 321| 1195| 7753| 10 RTD| 267| 0| 322| 1166| 7753| 10 May I accept this result as good? Or some bugs are in RTAI?

Somewhat strange, since latency has aperiod of 100000 ns, which is not overtaken by a max overall latency of 32043 ns. Let it run longer, under intense Linux load, and see what happens. BTW, have you disabled CPU frequency scaling (CPU throttling) BIOS/Linux config?

I'm wondering about overruns in latency test, are they normal?
