GraalVM performance vs C++

GraalVM is a JVM with multiple change: the graal compiler. It is intended to replace the C2 compiler (server mode) in front of HotSpot . Truffle a library that you can implements to make JVM polyglot ( there already a number of language that are supported like js, R, Ruby…)

Native Image is a technology to ahead-of-time compile Java code to a standalone executable, called a native image . This executable includes the application classes, classes from its dependencies, runtime library classes, and statically linked native code from JDK.

Yes. Kotlin/Native is available as a part of Kotlin project. It compiles Kotlin to native code that can run without a VM .

The GraalVM Compiler is a modern Java just-in-time compiler. It complements or replaces the existing compilers (C1/C2 in HotSpot) . In contrast to those existing compilers, the GraalVM compiler is written in modular, maintainable and extendable fashion in Java itself.
