My JavaFX app is managed by efficiency cores once reduced in tray icon.

[Davide Perini]

As title.
I'm pretty sure that my JavaFX app is managed by efficiency cores once 
reduced in tray icon since its performance drops significantly,
if I open a window and leave it open, the app goes at max speed on 
performance cores.

Is there a way to set the app runs on performance core even without 
leaving a window opened?

Thanks
