Java 8 on UDOO

The performance of OpenJDK 8 on UDOO (Archlinux) is not that great when compared with Beaglebone Black:

$ uname -a
Linux maggie 4.1.3-1-ARCH #1 SMP Wed Jul 22 18:44:39 MDT 2015 armv7l GNU/Linux

$ java -version
openjdk version "1.8.0_51"
OpenJDK Runtime Environment (build 1.8.0_51-b16)
OpenJDK Zero VM (build 25.51-b03, interpreted mode)

$ time java -XX:+TieredCompilation -XX:+AggressiveOpts fastaredux 25000000 > /dev/null 2>&1

real    6m52.692s
user    6m52.095s
sys     0m0.480s

Time to download  the Oracle JDK 8 for ARM.  Same as the case with BBB and Raspberry Pi, the result is much better:

$ java -version
java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b07)
Java HotSpot(TM) Client VM (build 25.51-b07, mixed mode)

$ time java -XX:+TieredCompilation -XX:+AggressiveOpts fastaredux 25000000 > /dev/null 2>&1
