It should be considered - infact - that ''OpenJDK Zero VM is an interpreter only JVM''. It's easier to port because it has no architecture specific assembly code but, on the other hand,
it's not performant because it has no architecture specific assembly code.

* <b><i>CaffeineMark</i></b>: according to the <b>Pendragon Software's CaffeineMark'''™''' ver. 3.0</b>
** the test was performed without independent verification by Pendragon Software and that Pendragon Software makes no representations or warranties as to the result of the test
== Benchmarking = Test results ===
The benchmarks have been run on the same platform and same cpu: the different JVMs was decompressed in the ''/home/root/java'' directory of the target and started manually.

The following tests have been performed on [[:Category:SBC-AXEL | SBC-AXEL]] equipped with:
* '''DXLM0193''' SOM
* i.MX6 Dual Lite processor @ 792MHz
* 1GB DDR
* boot from SD card (u-boot, kernel and root file system)
