  1. Yeah he didn't even mentioned SIMD, or how to break dependency chain, to give the CPU more room for speculative execution, or how to optimise the cache line usage, by using a DOD design, those are where the bottleneck usually occurs, if you look at what the cpu is doing most of the time in poorly optimised software the CPU is waiting to get data from the cache.
