Nice article, but it was probably heavily machine-translated with little human intervention. There is a message that says "Code Language: JavaScript" all over the place, but the code examples are actually in Rust, and the last (unnecessary) one is in C++.

To me, there is nothing that can beat CSAPP on this topic.

It´s a shame that the last edition is from ten years ago, although to be fair I actually only read the 2nd and only skimmed the 3rd one. Still, would be nice to get an update using ARM.

This is for me a basic knowledge for writing really-performant code. But I am surprised, that out-of-order execution isn't mentioned. And this approach is a big deal in modern CPUs.

Also important to know that if you're accessing disk, database, or network those are so slow that this stuff probably doesn't matter.
