Arch Linux with Racket v8.11.1. Starting a REPL takes almost a second and a simple hello world 300 ms. (No use telling me I should do x, y, z. A language that doesn't get it right by default is not for me.)
A second indicates something is wrong. Most likely the `raco setup` part of the installation was skipped. Try `raco setup` and see if it helps.
[I think, there were a snap at some point that had problems.]
