For simplicity, let’s say you might have a single-CPU system that helps “dynamic frequency scaling”, a characteristic that permits software program to instruct the CPU to run at a decrease velocity, generally often known as “CPU throttling”. Assume for this state of affairs that the CPU has been throttled to half-speed for no matter cause, may very well be thermal, may very well be vitality effectivity, may very well be as a consequence of workload. Lastly, let’s say that there’s a program that’s CPU-intensive, calculating the Maldebrot set or one thing.
The query is: What share CPU utilization ought to efficiency monitoring instruments report?
Ought to it report 100%, or 50%? That is like asking what facet of the mattress is the entrance, and which facet is the again – you can also make legitimate arguments both means, and no person is incorrect or proper.
