I'd like to come back to this email. I am starting to see similar issues
with my machine. When running the macro in the foreground it is
significantly faster than if I switch to my browser, document, texteditor,
or even Activity Monitor and let FIJI run in the background.

I have disabled AppNap as below and it makes no difference.

It seems that people are starting to see this in other programs too,
including Matlab.

https://apple.stackexchange.com/questions/108897/might-mavericks-interfere-with-long-computations
https://discussions.apple.com/thread/6050740?start=0&tstart=0
http://compgroups.net/comp.soft-sys.matlab/matlab-and-app-nap-on-osx-mavericks/2127523

I'm not sure if the Matlab guy actually figured it out or if figure(h) is
related to how images are drawn on OSX in ImageJ.

Does anyone else have any ideas or a way to more rigorously test the
difference and understand what's going on?

Like Sarah, I expect ImageJ to run full tilt until it's finished, not run
at 50% of speed because I'm looking at a text file trying to fix another
macro.

Thanks,
Brandon
