I see that if I change the mode from active to passive and back to active, I end up in active powersave, not active performance. Changing the governor to performance does reproducethe original performance. Still, I have the impression that the performance with passive/schedutil is excessively bad because the frequency is excessively low. But my machines are not available at the moment, so I will have to try again tomorrow to see what exactly is going on. julia
