Re: Raspberry Pi + JavaFX 3D demo
Hi Niklas, thanks for your answer. I looked in the current code form github (RoboVM 0.0.3) and found a „Level“ enum with -o3 optimization flag... so are you working on the optimization support for LLVM?

Re: Raspberry Pi + JavaFX 3D demo
I think these are the sample apps: http://interactivemesh.org/testspace/j3dmeetsjfx.html I take that back, the PI HotSpot numbers are generally faster than the RoboVM iOS numbers (but RoboVM is faster than HotSpot when run as an interpreter, obviously). We need to get our benchmark open source (we call it VMBenchmark) so that we can host accurate numbers on the WIKI and everybody can run it on their own systems.

Re: Raspberry Pi + JavaFX 3D demo
Here's my acid test, put a square grid of circles in a scroll pane. Scale
up until pain is felt.
GridPane gp = new GridPane();
//int size = 3;
int size = 10;
//int size = 32;
// int size = 100;
//int size = 317;
for (int x = 0; x size; x++) {
for (int y = 0; y size; y++) {
//Pane p = new Pane();
//p.setStyle(-fx-background-fill: blue;);
//p.setMinSize(20, 20);
//Text p = new Text(x + x + y);
Circle p = new Circle(50, Color.rgb((x0xf)*16, (y0xf)*16,
128));
GridPane.setColumnIndex(p, x);
GridPane.setRowIndex(p, y);
GridPane.setMargin(p, new Insets(5,5,5,5));
gp.getChildren().add(p);
}
}
gp.setCacheHint(CacheHint.SPEED);
ScrollPane scrollPane = new ScrollPane(gp);
scrollPane.setMinHeight(400);
scrollPane.setPannable(true);
My actual use case is a bit more involved (and it includes expensive
non-graphical calculations that make an intel core duo cry) and I've found
the windows box can handle two to three more orders of magnitude before lag
moves from unpleasant to unusable.
p.s. I really dig the scroll pane on skin on the touch screens. Complete
with over-drag and hidden unless dragging scroll bars. Well done.

Re: Raspberry Pi + JavaFX 3D demo
Have you tried running with the perf logger turned on? -Djavafx.pulseLogger=true This will tell you a little something about where the time is spent. It might not be detailed enough, but you can then put additional log statements in the code to get more direct answers to questions about where the time is being spent.
