Cliff Click walks through a small performance example on a modern out-of-order CPU. He covers pipelining, ILP, CISC vs RISC, multicore, and why cache misses and the memory subsystem dominate performance.
Recommended as an accessible refresher on how modern hardware and caches affect software performance.
