TL;DR — Ulrich Drepper’s 114-page tour of the memory hierarchy — RAM, caches, NUMA, TLBs — and what it means for writing fast code. Posted twice in the thread.
How much weight it carries: A standard technical reference from a Red Hat engineer. Some hardware detail has aged since 2007; the principles have not.
