Yeah DrRacket is fairly slow unless you have a powerful computer. I recommend just using a text editor and making use of XREPL, see: http://docs.racket-lang.org

Yeah DrRacket is fairly slow unless you have a powerful computer. I recommend just using a text editor and making use of XREPL, see: http://docs.racket-lang.org/xrepl/index.html?q= http://docs.racket-lang.org/xrepl/index.html?q= tl;dr, open up the normal repl by typing "racket" and then type (require xrepl) and then ,install! (leading comma denotes an xrepl command). Then when you want to interact with a file you can do racket -i $file to interact with it using xrepl. If you're wondering why this isn't just the default, I think it has to do with the readline license.
