How well does GEF scale? We're evaluating using it for a project that
may have hundreds of nodes in the diagram. (Large database schemas for
example.) Has this been done and what are the results?

Thx,
Max

maybe you could write some java code to one of the provided GEF examples
that adds hundreds of nodes. I think the schema example has a
ContentCreator class where you could add some looping.

Some clients are creating as many as 10,000 figures and editparts.

I use graphical datasets with several 10.000's of objects. When the
'diagram' is zoomed out, and a lot of graphical objects are visible, I found
out that performance is only acceptable of you implement your own
UpdateManager. The default DeferredUpdateManager repaints too many figures.

I also needed to implement and maintain a spatial index in the layer figures
to speed up finding editparts under the mouse cursor.

In your application, are all 10,000 objects siblings? In the example I was
thinking of, there is lots of nesting, so the nesting helps with tree
pruning.

Yes, I have several layers, where each of them can have up to several
10.000's of figures. Within such a layer, these figures are sibblings
indeed.
