I'm not sure of any definitive guides, but it'd be help to have an idea

is probably a good place to start, but I'll admit I've not read it.
Either way, searching the net for any phrases in my attempted

sorts of optimisations made - it assumes a long-running JRE instance.
You are running Hotspot version 19.1-b02 in mixed-mode. Mixed-mode
means that it will sometimes compile Java bytecode down into native
