CPU Performance Optimization Using Top‑Down Micro‑architecture Analysis (TMAM)

The article demonstrates how Top‑down Micro‑architecture Analysis Methodology (TMAM) can quickly pinpoint CPU bottlenecks—such as front‑end, back‑end, and bad speculation stalls—in a simple C++ accumulation loop, and shows that applying targeted compiler, alignment, and branch‑prediction optimizations reduces runtime by roughly 34 % while increasing retiring slots.
