I promised this test for Arindam, to fully implement the Guimark http://www.craftymind.com/guimark/ testcase in JavaFX 1.2
On both Windows and OSX 10.5 on my powerbook, I score around 4-5 fps. The slow framerate comes mostly from text layout, if you go into Holder.fx and comment out the following line near the bottom
wrappingWidth: bind width-12
you will see the framerate jump to roughly 40 fps.
This test is implemented using the same constraints as the Silverlight, HTML, and Flash testcases. I didn't implement the abilty to ping the charting result of the test when it's run, since I don't know how to launch the browser with a url from javafx
