I tested my application on Java 7 on Mac OS X. It works noticeably sluggishly. I used VisualVM to try and track the bottleneck and find the linear interpolation as the culprit:
g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
To some extent this makes sense, of course. Using interpolation will slow down. But I do not see such a dramatic difference between using and not using interpolation in Java 6 on OS X. In Java 6, the difference was almost negligible. (The images below represent the VisualVM profile paintComponent()after doing standard animation in my application.)
With interpolation:
Without interpolation:
But in Java 7 on OS X, the difference is much more noticeable:
