This maybe can be useful :
Protip: Java (icedtea or Sun JDK, that I've tested) on Linux 3.6 appears to have some issues, and will often eat up all available CPU cycles.
When building Android, that's especially noticeable when something is being run through proguard, and makes build times shoot up (not to mention unusable machines for the duration). If you're seeing java/javac processes use ALL the cores for visible periods of time while building android, and your host is on linux 3.6, try echo never > /sys/kernel/mm/transparent_hugepage/defrag
