Hi,
    Is there any document or tutorial about how to interpret JavaFX Pulse log 
message? I turned on Pulse Logger for my application and see the log message as 
follows,

PULSE: 575 [143ms:20ms]

        NGRegion renderBackgrounds slow path: 26
        Nodes rendered: 212
        Nodes visited during render: 227

There is a lot of "Slow background path for null”. Is that indicating a 
problem? If so, how can I fix it?

Thanks,

Tai
