This helps improve the peak performance of long-running applications. Some optimizations reduce object allocations which lowers the load on the garbage collector. This approach ensures that code in hotspots run extremely fast thanks to aggressive inlining, partial escape analysis, and other advanced optimization. Compilation is performed incrementally during program execution with extra optimization applied to code that is frequently executed. ![]() When using GraalVM in JIT mode, the JVM uses the GraalVM Enterprise JI compiler to create platform-specific machine code from Java bytecode while the application is running. GraalVM’s Truffle language implementation framework works with the GraalVM compiler to run JavaScript, Python, Ruby, and other supported languages on the JVM with outstanding performance. ![]() ![]() The core of the GraalVM project is the advanced optimizing GraalVM compiler, which is used as a just-in-time (JIT) compiler for the Java Virtual Machine (JVM) or by the GraalVM native image feature to compile Java bytecodes ahead-of-time into native machine code. GraalVM started in 2011 as a research project at Oracle Labs to create a runtime platform that can run multiple programming language with high performance.
