A performance confuse of thumbnail [message #1786218]

Hi,
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?

Hi,

The outline view is provided by default by GEF. Indeed, we noticed this performance issue but since GEF 3 is not maintained anymore, this issue will probably not be addressed.
The only workaround is to close this view for diagrams with a huge amount of figure :-(

Regards,

Florian

Hi, Florian Barbin
Thanks for your reply.
I debugged the process, It seams that, the thumbnail paint all the figures recursively, while the ToggleUpdateManager.performUpdate() only paint part of the figures, according to a HashMap named dirtyRegions which stores the affected picture and its dirty region.
