You missed "without optimizations on".
This is important, because most often during development you want fast compilation times more than you want fast code.
That still isn't a paradox. Furthermore it still makes sense: a language designed to generate the fastest code has constructs that cannot be compiled quickly, even without optimizations.
But some of it is implementation problems.
