It depends on the compiler you use. According to 3rd-party benchmarks, MSVC compiler is usually faster than GCC, but produces better (both smaller and faster at the same time) code. But it can be incredibly slow if you enable link-time code generation (this feature is useful when you want the compiler to optimize as much as possible, i.e. when optimization is more important than compilation time).
