I found that, when i editing model with sirius diagram, if i open outline overview, the editing performance will be worse. I analysed the source code, found the ToggleUpdateManager.performUpdate() is responded for painting the sirius diagram; the ThumbnailUpdater.run() is responded for updating the outline overview. Is my analysis correct or not?
My confuse is that, why the ThumbnailUpdater.run() costs more time than the ToggleUpdateManager.performUpdate()? Did not the ThumbnailUpdater.run() just scale down the picture which ToggleUpdateManager.performUpdate() painted?
