The compiler is definitely also slow. As far as dynamic languages go, however, Racket is very fast in general and you can push it very far. > use in production was not its main focus. What makes you say this/what do you think it's missing as far as "use in production" goes? Instrumentation? Something else? I've deployed both production web apps and desktop apps with Racket, and the experience has been as good or better than other languages I've deployed similar things in.
