Advanced languages can compile quickly - it depends on the feature set chosen. For example, do-notation is an advanced feature not found in most languages, but it compiles quickly as it is syntactic sugar. Operator overload, on the other hand, might require a solver and thus compile slower. It's not a particularly advanced feature, however. Binary optimization passes do not make the language any more advanced (on the user side), but will slow down compilation. Advanced design and compile-times are pretty orthogonal.

As for maintainability, it's not clear to me that reams of imperative code is easier to maintain than something terse and declarative. In fact, probably the opposite.
