How to check CPU usage in DevTools Performance?

Question

JavaScript

In DevTools (Inspector), in the Performance tab there is a CPU graph:

1. Is it the load of the entire CPU or just what kind of load does this site have? (And then I'm testing a simple animation, and the workload is 1/3, although the PC is normal)
   
2. Why no interest? (Do I have to somehow calculate the workload in milliseconds or what? It's not very convenient to track the load through the task manager
   

Answer 1

Well, in the same place there is a lot of everything, and FPS will show you and the processor load and you can even artificially throttle the processor, getting a slowdown at times in order to emulate weaker devices.
