How about instead aiming for 1000x as fast, so that it's as fast as a statically-typed language? (Google's pure Python Protobuf implementation is literally 1000x slower than their Python front-end that wraps the C++ Protobuf library...)
Oh wait, achieving native speed is close to impossible for a dynamically-typed language.
