NetBeans profiler allows for defining result categories (or "Areas of Interest"). Currently there are categories defined for JavaEE applications and JavaSE applications. For more info about the categorization feature you can watch a podcast @ http://www.netbeans.org/download/flash/netbeans_60/profiler/profiler.html (the intersting part starting at around 1:00)
The categories for JavaSE applications include eg. IO, Swing Painting, Listeners processing etc. It will make sense to add JavaFX specific categories for JavaSE applications as JavaFX applications will basically be a standard JavaSE ones with jfxrt.jar on classpath (simply put).
An example of JavaFX specific categories would be Rendering, Pulse processing, Property bindings etc. The actual number and meaning of the categories will depend on the JavaFX runtime implementation.
