OB is quite complex thing, and its hard to understand what it does for outsider :) I just identified a few points, which can improve rendering speed by a certain amount: a test code: MessageTally spyOn:[self fullDrawOn: World assuredCanvas]. where 'self' is a mid-sized browser window displayed on screen, non-obstructed with another morphs (Watery 2 theme). - default. 60 ms - with override in SystemWindow>>drawDropShadowOn: aCanvas to do nothing: 51 ms - with override in OBMonticelloPackageNode>>classCategories to return cached collection 45 ms so, here we won 15 ms, which is 1/4 of total rendering time by changing just two methods. Of course, numbers may vary for different browser sizes (more time spent on fills), and different data viewed (more lists traversal etc). I'm attached the changeset with patched method, but i'm not sure about cache - it should be updated when user adds new category, and i don't know how to hook to such events to flush the cache. I think that people who know OB better could do that with ease. > Stef > > > On Feb 7, 2009, at 6:31 PM, Ramon Leon wrote: > >>> The biggest concern I have right now is speed.
