Fast and Compact: Reducing Size of AOT-Compiled Java Code without Sacrificing Performance

GraalVM Native Image is a technology that compiles Java applications to native executables ahead of time (AOT). Due to highly aggressive optimizations, it is possible to reach a peak performance similar to that of a regular Java application executed on a Java Virtual Machine (JVM) and its Just-in-Time (JIT) compiler. The advantage of Native Image is much faster start-up when compared to the JVM and the JIT compiler. However, binary files resulting from Native Image tend to be quite large.
