Some Early Tests Of The Eclipse OpenJ9 Java Virtual Machine

With IBM's newly open-sourced J9 Java Virtual Machine as the Eclipse OpenJ9, I've run some quick benchmarks to get an idea how its performance is comparing to the de facto Java Virtual Machine, Hotspot.

On two Linux boxes today I tried out OpenJ9 as packaged with OpenJDK 9 and compared its performance to the current OpenJDK 9 Hotspot build and also as an additional reference point was the OpenJDK 8 Hotspot build. The three builds of OpenJDK Java were obtained from their prebuilt binaries page.

One of the systems used for this quick Java JVM benchmarking was an Intel Core i9 7900X box running Ubuntu 17.04 with the Linux 4.13 kernel.

While the other system was a two-socket Tyan server with Xeon Gold 6138 processors and running Debian GNU/Linux 9.1.

On both systems the three OpenJDK releases were tested and a few of the available Java benchmarks were run via the Phoronix Test Suite. If you would like to see other Java benchmarks added to PTS, contributions are certainly welcome.
