The synchronized block is present in MouseInput as well as KeyInput implementations it doesn't appear to reduce performance there. To remove contentions, I am not starting my thread implementation which feeds this queue. The only code which is using this synchronized block is the UI thread(JMonkey) looking for events.

Dardzull has kindly checked my code on his RaspberryPi - Apparently he is using the Armel image with Sun's Java - it runs at 60 FPS
 on his machine.

Same code On mine which runs in Raspian wheezy (Hard float) and Open JDK 7 (with and with out jamvm ) I am only getting 25FPS
