OpenJDK 8/11 vs. GraalVM 20 vs. Amazon Corretto JVM Benchmarks

When it came to the SPECjbb 2015 benchmark, GraalVM 20.0 Java 8 and Amazon Corretto 8.242.08 were the front-runners followed quite closely by the upstream OpenJDK 8. The builds targeting newer versions of Java were much slower.

When taking the geometric mean of the 32 tests that were carried out, OpenJDK 8 upstream actually came out the best overall followed quite closely by GraalVM 20.0 Java 8. Meanwhile the Java 11 version of GraalVM 20.0 was by far the slowest. On the Amazon Corretto front, version 11 was quite similar to OpenJDK 11 upstream but its Java 8 implementation was coming out similar to that slower Java 11 milestone.

When counting simply the number of first place finishes, GraalVM 20.0 Java 8 had the most wins at 40%. The most performant JVM implementation really depends upon the workload(s) most important to your use-case.
