<p>Spinner use a lot of CPU. When spinner is animated CPU is about 20% otherwise its 1-3 %.<br>
Thats the old problem with the JavaFX progress indicator. I optimized in the old version those classes to use less CPU. No need to fix it for that release but we should either try to find an alternative or fix the CPU issue in follow up releases. Shame on Oracle that they are unable to build such a simple animation with performacne in mind.<br>
