https://en.wikipedia.org/wiki/Hardware_performance_counter can help with noisy neighbors. I am still getting into this.

Yes, that can help with detecting how much cpu was actually used during the run. But it doesn’t influence benchmark results. Not sure how exactly to use it for doing subsequent runs and comparing final performance. Then this needs to be extrapolated to final performance in production.

		Yeah, what you want to know is which change caused the slowdown, or maybe improved the performance and reasonable metric behind it (for example frame-rate for a game, or something like this).
