I'm sure others can do better than this, but:
1. Optimization quality has varied widely over recent compiler
versions
2. The compiler has *many* optimization options so it's easy to
overlook some (e.g. inlining limits)
3. g++ has never been known as a compiler with extremely low
abstraction penalty.
