GraalVM for Endless Performance
summary
GraalVM as released for JDK 22 brings polyglot runtime support (JavaScript, Python, Ruby, R, JVM languages like Java/Scala/Kotlin/Clojure and LLVM-based C/C++) and performance improvements. The talk explains GraalVM architecture in the Java ecosystem, covers Graal JIT (C2), GraalVM Native Image AOT compilation to reduce startup time and memory, and gives concrete build recommendations such as profile-guided optimizations (--pgo), setting a max heap for predictable memory, and using -march=native; it also mentions using GraalVM with Spring Boot and microservice frameworks.
