Is there an issue for the client-side AOT-cache of libraries? This was discussed some time ago in clojure-dev slack. Would like to see that moving forward.
Currently, despite REPL spins up fast, all libs are distributed as sources and get re-compiled every time when they are loaded into REPL adding easily 10+ secs for just to spin up a batteries included web server (or a test runner). Caching compiled classes for libs that haven’t changed between REPL sessions would help a lot.
