Thank you, Dave, for replying. I will check out the link.

Do you have specific advice/experience for Linux's g++ that might improve or explain what we're seeing here?

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.
