A workload pinned to cpu6 runs at 4032000 with boost off and 4723200 with boost on, 3.14 s against 2.50 s. 2/2: # cat policy6/scaling_max_freq 4032000 # echo 1 > boost # cat policy6/scaling_max_freq 4723200 # echo 0 > boost # cat policy6/scaling_max_freq 4032000 One observation: policy6/cpuinfo_max_freq still reads 4723200 after boost is switched off again.
