Comment 8 for bug 687567

My testing reveals thats this is not specific to the menubar. Menu's in general are slow under Unity whether they are in the panel or right click menus inside an application window, that causes application slowness which is very much notable on slower devices like netbooks. also (this might not be related to this bug) dialogs inside an application are slow to appear when compared to the classic desktop all in all there is certainly something wrong in the picture that is causing the slowness.
