This seems like a really short blog post on the subject. Is there anything that goes into greater detail, esp. with Linux perf tools?

You can also visit easyperf.net (my blog). If you like Linux perf the same way I do, you will like it. Here are some links:

- https://easyperf.net/blog/2019/04/03/Precise-timing-of-machi...

- https://easyperf.net/blog/2019/02/09/Top-Down-performance-an...

But in the end, my almost every article contains a Linux perf use case scenario.

Yes, there is essentially nothing to see, here, beyond "measure".

Thanks, and don't forget to measure. :)
