Again, I am biased. But the article explains mem translation in fairly simple terms, hammers the main advantages of HPs (better use of the TLB, simpler and smaller PT). Explains clearly what how much mem the TLB can cover, what a page walk is and how much time it takes (before even loading actual data), the importance of the cache wrt PT. It shows some perf numbers of random vs iterative mem accesses.

I don't think you'll find many articles that detail these points. Now, they might be trivial to you and that's totally fair. But the goal is to address a wide audience. Additionally, the article is not addressing how to use HPs but that's for part 2.

Wrt to other points, I certainly agree they are important topics to explore. I would add using perf is super important to easily access the perf counters
