This is wrong. There is no rule that says that you cannot write fast applications with fast builds. It is just that we got used to C++'s slow build times. This sort of thinking even falls flat on its face when you consider that C provides similar optimization opportunities as C++ (and in pretty much every modern compiler it uses the same backend and most - if not all - optimizations) while compiles much faster. But beyond that most of the codebase of a decently sized application does not need more than the most basic of optimizations - it is only a tiny tiny fraction that needs that, yet with modern C/C++ (and most other) compilers, the entire codebase suffers for it (i think only Visual C++ allows you to control optimization settings on a per-function basis, but i haven't encountered any codebase that actually uses this outside of temporarily disabling optimizations for debugging and/or working around bugs).
