Racket, in general, is not slow apart from (a) startup and (b) some things that use Typed Racket (c) the compiler. <br />2. One thing that makes Racket startup seem slow is not compiling things ahead of time; being able to do this is an advantage over something like OCaml, but it ends up being portrayed as a disadvantage (this is the macro expansion at startup Jon mentioned).<br />3. Past that, startup time is worse in Racket than eg in Python, but not a lot.</p>
