Maximizing Performance with GraalVM

on YouTube ↗56m

" summary

GraalVM runs Java two ways: the Graal JIT yields higher throughput and can optimize through layers of abstraction so an objects.hash version performs like a hand‑written loop thanks to partial escape analysis. Native image ahead‑of‑time compilation produces snapshots that start in milliseconds (demo shows ~25 ms startup) and cut total process memory (example ~32 MB footprint versus ~150–170 MB for JIT), integrates with Micronaut/Quarkus/Spring tooling, and requires explicit configs for reflection and dynamic class loading.
