JavaFX - very cool, very slow

Bubblemark, a simple 2D animation demo, is becoming a code sample to compare performance of different RIA frameworks. They now provide on their website about 7 tests, including a recent JavaFX test, that concluded in very low values.

Although JavaFX is still in alpha bits, this are the summary:

JavaFX — 14 fps
Firefox + Silverlight (JavaScript) — 56 fps
Firefox + Flex — 62 fps
Adobe AIR — 62 fps
Firefox + Silverlight (CLR) — 99 fps

It is 4.4x slower than Flash and 7x slower than Silverlight (CLR-based variant).

There are already reports they are working on increasing it speed by high numbers.
