Bootiful GraalVM
summary
GraalVM + Spring Boot compiles a Spring app to a self-contained native image (65 MB unzipped, 25 MB zipped binary) and shows concrete wins: first-request CPU drops from ~3.5s to ~0.03s — about a 100x CPU reduction — and memory from ~500MB to ~58MB; under 100k requests native uses ~3.7s and 170MB vs JVM 10s and ~1GB, and O2-optimized builds beat JIT at a million requests. Demos include native-image build reports, runtime hints for reflection, multilingual JS+Python+WASM embedding, and an Llama‑3 Java inference example; Oracle distribution is free with binary‑resale caveat.
