I’ve wanted to give GraalVM and its native-images a try but haven’t yet. Do you have any experience with it?

  Yes - I once wrote an AWS lambda that was having issues with cold boot times, so I compiled it to a binary and bada bing bada boom, boot went from 2 seconds to about 200ms. It's not a silver bullet though - some reflection features aren't supported, and reflection in general requires a bit of config at compile time to make sure all the required classes are loaded. This can make some plugin architectures unworkable, although I maintain that if you need reflection for pluggable code, you're probably doing it wrong.
