I'm sure others can do better than this, but:

  1. Optimization quality has varied widely over recent compiler

  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.
