1. Run Stunner Showcase in Chrome browser 2. Open Task Manager (Shift+Esc) 3. Look at Memory usage and JS memory usage (use right mouse button on table header to open additional columns) 4. Try to open and to close some Processes Actual Result: 1. After project start it tab takes: Memory: ~340 Mb JS Memory: ~200 Mb 2. With one opened evaluation process: Memory: ~364 Mb JS Memory: ~221 Mb 3. After some interactions with process elements: Memory: ~445 Mb JS Memory: ~229 Mb 4. If now you close evaluation process: Memory: ~402 Mb JS Memory: ~235 Mb 5. Open/Close evaluate process for some times Memory: ~620 Mb JS Memory: ~270 Mb If you will draw something for every Open/Close iteration the results will be even worst. I achieved 1+ Gb of used memory. Also if you click Ctrl+Shift+J (open Developers console) and navigate to Elements Tab you can found a lot of repeated SVG pictures and other html elements. (Even if all instances of Stunner are closed and only WB is shown). Expected Result: Browser will clean up memory after closing Business Process
