Expansion of a package in the Package Explorer view is slow when alt+click is used. The package contains 3 Java classes in the context and 8 Java classes not in the context. By slow I mean that I can see the expansion occur. It should appear to be instant.
Can you describe what you mean by "you see the expansion occur"? Is this a problem with the way the UI is redrawn or is the delay caused by expensive computation, e.g. Java model loading? On Gtk it feels instant although I can't tell if there is a 200 ms delay.

I mean that I can see elements appear one after the other, with enough delay between them that they don't appear together. > Is this a > problem with the way the UI is redrawn or is the delay caused by expensive > computation, e.g. Java model loading?

David, are you still seeing this?
It's not too bad when expanding a single Java package, however when expanding the root to expose filtered projects (I have 481 in my workspace) it's quite slow.
The implementation is inherently slow for a large number of resources and I don't see this changing in the near future.
