The Project Explorer takes a long time to expand the nodes (it takes long the first time because of plug-in activations, ) Try expanding the nodes (Dynamic Web Project, EJb project, Enterprise...) Even after that try expanding a project node it takes time. Its a generic problem for which has Eclipse has a soln in place from 3.0, Lazy tree expansion The DeferredTreeContentManager is already in place in eclipse I am sure the Project Explorer guys may have already encountered this solution before, I am not sure why they have not implemented it. By playing around with it I have implemented it in the project explorer in my workspace, its not too hard, I only had to implement 2 classes and make a couple of changes here and there. The treeviewer expands very quickly and is more UI responsive. Let me know if you need any info. I will send the files to Michael Elder too.

The CN framework supports ITreeContentProvider and ITreePathContentProvider. There is a DeferredContentManager for ITreeContentProvider, but none for ITreePathContentProvider. As such, I don't think that this can be fixed without significant code from the ground up. Therefore, I do not think that this can be contained in 3.2.

Hey Boris, Do you think this is worth doing? I mean will it provide a substantial performance benefit and is the amount of work manageable. I don't know too much about the UI Deferred support stuff which I assume works somehow with the SWT.VIRTUAL trees. I saw somewhere though that Windows does not really support virtual trees. I would be interested in your thoughts.
