问题
I was able to install Java8 + JavaFx on my Raspberry B+ following this tutorial http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/RaspberryPiFX/raspberryfx.html and thanks to this suggestion JavaFx Ensemble on Raspberry pi
I'm able to run Ensemble8 and also a very basic JavaFx test that open a blank stage. In every case the app is very very very slow. Moving the mouse from one point to another takes several seconds!!!!
Is this performance normal??
Thanks
回答1:
The dalvik-sdk.zip that was previously available at https://bitbucket.org/javafxports/arm/downloads contained experimental code for mobile/embedded. I removed that code, and it works at normal speed again now.
You can download the new sdk at the old location: https://bitbucket.org/javafxports/arm/downloads/armv6hf-sdk.zip
Sorry about the confusion, I hope this fixes the issue?

I've tested Ensamble8 in both JDK8u33 and JDK8u06, and you are right, now the application goes really slow, while in the previous JDK it went well (considering it's a big application), but without any lag on the mouse.
Maybe it is because jfxrt.jar is loaded as external sources, or maybe because there's a huge logging to console while moving the mouse, so I suggest you create an issue on the repository, so they disable the logging in the next build, hoping this will help.
