The need for speed. What is GraalVM and how can it help you?

" summary

GraalVM replaces HotSpot’s C++ JIT with JIT written in Java, adds the Truffle language framework for blazing‑fast interpreters via partial evaluation, and provides SubstrateVM plus native-image (AOT) creates standalone binaries that cut a HelloWorld startup from ~0.7s to near C/Go speeds. Key optimizations include partial escape analysis, scalar replacement and lock elimination; TruffleRuby and Truffle-based Python/Node implementations outperform traditional interpreters. Native‑image uses a closed‑world model (no runtime class loading), has CE/EE feature and support gaps (Spring integration, debugging, Oracle licensing) to consider.
