I wrote this blog series for the second edition of my book titled "Performance Analysis and Tuning on Modern CPUs". It is open-sourced on Github: perf-book. The book primarily targets mainstream C and C++ developers who want to learn low-level performance engineering, but devs in other languages may also find a lot of useful information.
