1s to print hello world is an awful lot I would like to point out.

  Upvoted you because I agree. JVM has many strong points but I don't think anyone is disputing that startup time is a weakness. I've used some java tools that you invoke from a command line and I'm always slightly annoyed by how slow they are. As an aside - I was trying to reduce -Xmx to improve HelloWorld startup (lol idk...) and Xmx smaller then 1024k and it couldn't start up with less then 1024k so there's that. On my windows computer (also I barely know what I'm doing so probably even timing it wrong).

    Worry about -Xms rather than -Xmx for startup times. I suspect there are ways to make it faster (e.g. there's a nashorn runner that starts up appreciably faster than "proper" java), but the main use case for java is server-side programs that run for days or weeks between restarts, so it's optimized for that use case.

  Sure it's a lot, but clojure startup times are significantly longer than that.
