Yes. Idle indicates the fraction of time that the CPU is (figuratively) “fiddling its thumbs”, having nothing to do.

Macbook air M1 cpu slowdown Hi, my M1 macbook air has had a sudden slowdown. It's so bad that safari tabs literally take 2 whole seconds to open and when I'm doing a "power intensive" task, like video editing, gaming, or doing a benchmark. It gets so slow that safari literally freezes, and opening a new tab takes 10 whole seconds.

This is normal. Do you think it should be something else?

No no, not necessarily. I was simply curious about the Idle percentage. Thank you.
