Slow start javafx GUI application, how to speed up?

Question

Java

Any even the simplest application of two buttons on javafx starts in about 2-3 seconds. (Win, Ubuntu)
A simple mono application in ubuntu starts many times faster and is comparable in speed to c++ applications (qt)
What are the ways to make JavaFX start up faster?

Answer 1

- Try running with "-Djavafx.autoproxy.disable=true"
- Try "JavaFX-Feature-Proxy: None" in the manifest
- Java FX is almost like graphics in a browser, imagine how long it takes to load, run, render the GUI.
