I found managing production JVM is amazing. In fact, little other runtimes come close in my opinion. What don't you like about it?

For scripting, there's a lot of ways to script efficiently with Clojure, it's actually great for it as well. So, for most my scripts, I don't really mind waiting 1 second for them to start. That said, if you wanted them to start faster, using ClojureScript takes you under 100ms. And using Joker (https://github.com/candid82/joker) takes you under 50ms.

When I need even faster startup for scripts and also need performant runtime, I've been using GraalVM to compile to native binaries, those start in under 10ms, and execute much faster than ClojureScript and Joker. That's a good strategy if you want to write things like a grep tool, or ls, or a linter, code formater, etc.
