On the same day as the release of Java 21, Oracle announced the release of GraalVM for JDK 21. GraalVM is a JDK that uses an alternative just-in-time (JIT) compiler but it also includes a Native Image module, a technology that allows Java applications to run as native executables, without the need for a JVM. This can improve the performance of Java applications in terms of speed, memory, and size.
At Oracle, they compared the performance of Native Image with JIT compilation, which is the default mode of running Java applications on a JVM.
