Java Benchmarks: OpenJDK 8 Through OpenJDK 19 EA, OpenJ9, GraalVM CE

Oracle's GraalVM CE was performing very well within some of the Renaissance benchmarks compared to OpenJDK.

OpenJ9 failed to successfully run some of the Renaissance benchmarks.

The geometric mean is for all of the Java benchmarks where they were successfully tested across all of the JVM versions/implementations under test. OpenJDK 18 and especially the OpenJDK 19 early access is looking quite good overall for performance and in some cases finally matching or outperforming the old OpenJDK 8 build. GraalVM CE also performed very well in select benchmarks as did OpenJ9 in a few select areas.

Or above is a look at the geometric mean for all of the results once dropping the OpenJ9 runs, since they failed to run some of the Renaissance benchmarks. This larger mix of data shows Oracle GraalVM CE being quite competitive with the performance of OpenJDK. OpenJDK 19 in its EA form is looking quite nice from a performance perspective. OpenJDK 19 GA is expected in September.
