title: Is JavaFX GUI heavy for the performance?
body: <p>I am learning JavaFX, and it seems very cool, but pretty nasty too. As far as I got it, the GUI is written in XML, and exported in the exact same form (not being converted or anything), and the XML is being read with <code>FXMLLoader</code>, every time the window opens up. Also, JavaFX has much more features than swing (rotating, 3D, etc). So my question is: </p>
  
  <p><strong>Is JavaFX significantly heavier for the performance, comparing to Java Swing?</strong> If it is not, then how heavy is it?</p>
