I've had similar performance issues on my macs (Air, mini, and iMac) since
upgrading to Yosemite and Java 8. There's been a few emails indicating that
the performance issues were Java 8 more than anything else, but the fixes
do not seem to work (mostly upgrading FIJI/IJ and Java). Most of my
performance issues occur when switching windows during a macro and it
appears accumulative. As in, the more images I open and close the slower
windows update/refresh, and yet previous images have been closed. It sounds
very related to the issues OP is having.
Oddly, when running in batch mode these issues do not happen. There is no
slow down so it's some sort of drawing issue, which may be related to video
drivers or the interaction of those drivers and Java. I really have no idea
though, I'm more of an end-user than a developer.
I'm running Yosemeite 10.10.5 on my iMac, 10.11.0 on my mini, and 10.10.5
on my Air, all with Java 1.8.0_60 (latest) and they all exhibit the
problem. I had better performance on 10.9.x with Java 6, but there's a push
to move to newer Java versions for security and performance (oddly enough)
reasons.
If anyone has a way to narrow down the issue and help the developers
isolate the issues then I'm happy to help because this really slows down
macro development for me on a relatively beefy machine (iMac).
Thanks,
Brandon
