" summary

GraalVM’s Substrate VM and native-image compile JVM apps ahead-of-time into single self-contained executables (Linux/macOS; Windows preview) that start instantly and use far less memory. Demo: Sieve of Eratosthenes — Go exe ~2 MB / 260 ms, JVM on HotSpot <100 ms, native-image exe <3 MB. Interop demo: naïve JNI matrix access takes ~5 s, moving the algorithm into a native-image library drops it to 70 ms (≈60× faster). Limitations: not full TCK, reflection config required, ARM support in progress.
