Raspberry Pi + JavaFX 3D demo

[Richard Bair]

Have you tried running with the perf logger turned on? -Djavafx.pulseLogger=true

This will tell you a little something about where the time is spent. It might not be detailed enough, but you can then put additional log statements in the code to get more direct answers to questions about where the time is being spent.
