I want to know what business anything running on a modern computer has taking that much time to start up. Aside from the fact that 5 seconds is an insane amount of time, this is before any user code has been loaded, so presumably your Clojure repl is executing the same 5 seconds of work every time it starts. Can't that be cached?
