The article explains why emulating x86's strict TSO memory model on ARM's weak model is costly, shows microbenchmark results for acquire/release vs. LRCPC loads, and describes how newer ARM extensions and Apple Silicon's TSO mode restore performance.

The author, coming from a TLA⁺/distributed‑systems background, finds the early chapters excellent for building intuition about CPU caches, memory ordering, and false‑sharing, but notes gaps (e.g., shallow coverage of C++11 atomics and MESI). The review is concrete, cites specific chapters, and offers prac…
