time(1) and CPU frequency scaling
Is it wrong to measure processes using
time(1)? In my particular case, it was wrong. But it really depends on what you want to know. You can also look at it like this: The fact that theuservalue increases and the frequency drops so much actually tells you that this might be a bit too much load for your machine.
