Hi Brandon & Aryeh,
I am fairly confident that the cause is attaching AWT menus bars, as I
outline here:
http://forum.imagej.net/t/mac-java-speed-issues/304/4?u=ctruedenSomeone with a technical background needs to investigate the potential
solutions to the issue that I mention in that post.
In particular, using the Apple-specific "Application.setDefaultMenuBar"
method is highly likely to fix the issue. However, as I outline here:
http://forum.imagej.net/t/mac-java-speed-issues/304/8?u=ctruedenIt would be a bit of work to add code to ImageJ2 to hot-translate the
ImageJ 1.x AWT menu bar to a Swing JMenuBar. The good news is that doing
this would have multiple advantages:
* The "grinding to a halt" performance problem would likely disappear.
* We would have a richer menu bar with icons for ImageJ2 commands that
provide them. ;-)
* The menu bar flashing when you switch windows would no longer happen.
The downside is that it is more complex internally, since we would need to
keep the JMenuBar internally synchronized with the menu bar that IJ1
believes is its menu bar (but in actuality is now never actually attached
to any windows).
There might also be unforeseen technical obstacles with my proposed
solution here. All in all, it would probably cost me several days to
explore and implement this fix, and I currently have other more urgent
priorities. But I will try to make time to do this work early this fall.
Regards,
Curtis
