GraalVM: Run Programs Faster Anywhere

on YouTube ↗52m

" summary

GraalVM replaces the JVM JIT with the Graal compiler to speed Java/Scala/Kotlin code (example stream benchmark falls from ~180 ns per op to ~10 ns, ~20x), runs dynamic languages via Truffle and an embeddable polyglot context (JavaScript, Ruby, R, Python, LLVM bitcode), supports mixing languages inside Spring and Node apps and debugging with Chrome DevTools, offers ahead‑of‑time native-image executables (demo starts in ~90 ms using ~25 MB RAM), and operators report CPU drops of ~8–10% (tunable to ~20%) depending on workload.
