To follow up on that, here are some strategies for reducing that time: 1. Start with Minimal Racket, install "math", then follow the steps above. That will just rebuild `math`, not everything that depends on it, since they won't be installed. 2. (Dangerous) Do the following: $ raco pkg update --no-setup --clone math # fast $ raco setup math This will only setup "math", and thus be faster, but will potentially cause other parts of the installation to not work correctly until you run "raco setup". Making the original commands go faster would require one of three things (in increasing order of difficulty): detecting that many zo files can be re-used from the previous installation in some fashion, making Typed Racket faster, or making Racket macro expansion more incremental.
