JavaFX graphic performance slow on Mac? Clock app

[Jim Graham]

I was able to verify the CPU usage on my retina MBP and further show 
that ES2 on Windows also consumes a similar amount of CPU:

Mac (using ES2): 20-25%
Windows (using D3D): 3%
Windows (using ES2): 20%

so this is definitely related to our use of OpenGL and not a Mac 
platform issue (though it did have a couple percent more overhead than 
the ES2 pipe on Windows, the bulk of the performance was ES2 vs OGL).

Can you remove the external dependencies on the date formatter from your 
test case and then submit a bug so we can track this issue?

I created a little clock app which uses between 25% and 80% cpu usage. But what’s the reason for? I though JavaFX rendering pipeline works on the graphic device? So why there is such a traffic on the CPU?
