I have recently been performing some benchmarks of the various Java Virtual Machines available on the Raspberry Pi ARM11 platform and thought I would share the results. I used this test suite: http://dacapobench.org/
Thanks to forum member chrisg on the Raspberry Pi forums who posted these benchmarks results for the previous Debian "Squeeze" image. The results listed below for the OpenJDK are taken directly from chrisg's post. I also ran these same tests on my Pi with Debian "Squeeze" and received very similar (maybe slightly higher) results.
The following JVMs are represented:
- Oracle SE 7 JDK (7u6)
- Oracle SE 7 Embedded JRE (7u4)
- OpenJDK Zero VM (6u18)
- OpenJDK Cacao VM (6u18)
The following chart includes all the tests performed and the resulting time in milliseconds that each test took to complete. Obviously the lower number the better :-)
I included a TOTAL line that sums up all the test results in minutes for each test case for rough comparisons, but please note that it does not compensate for the time missing from failed tests.
The test results are charted below for a visual representation.
I was particularly interested in the performance between the two available Oracle JVMs. The results (as expected) were almost negligible. The graph below illustrates the results of the two Oracle JVMs.
