Description djrowland 2015-08-18 00:26:07 CDT 
Since a couple of updates ago, Fiji seems to run very slowly. Having a small image set loaded, I noticed that scrolling through an image stack of about 22 slices, that there was a long lag time for the images to display. So there essentially was no smooth scrolling the images whereas in previous versions it was the case. I also created a macro to process DWI images in to ADC maps for MRI data. This macro now runs extremely slowly and is painful to use. 

I have read on the FIJI website that with the new updates there are issues with Fiji and Java on MacOSX. I mainly use Mac and it is now mostly useless for my purposes. If it would help I could upload data and the macro.

See:
http://imagej.net/FAQ#Why_does_ImageJ_run_so_slowly.3F

Is the problem resolved if you update to the latest version of Java 8? (1.8.0_51 as of this writing)

I opened system preferences and selected Java. It opened the Java Control Panel and I opened the about page. The about page displays that the current build on my system is 1.8.0_51-b16.
Comment 3 djrowland 2015-08-20 11:48:15 CDT 
That is interesting. I didn't check back on loading images and running my Macro. So I decided to do this after posting my comment. ImageJ is now snappy and quick like it used to be. The macro runs smoothly. I thought that I had checked that the version of Java was version 8. I am not sure what my system details were at the time it was running slowly. I guess by looking at what is reported in the bug it must have been version 7. 

The only thing to note is that when I zoom in on the images the scrolling does get a little sluggish but not like the other day.

thanks
Doug
