Measuring Performance
Using the Storyboard logger plugin it is possible to capture metrics detailing various aspects of a Storyboard applications performance. These metrics include screen, layer and control redraw times, action execution times and general event processing times. If a performance log file is captured as and saved with the file extension .plog (for performance log) then Storyboard Designer will automatically recognize it and open up a log file viewer that provides an organized display and base analysis of the performance events.
