Linda,
thank you for your support.
As I understand I have to wait for the GMF SDK 2.1.3 release to have benefits of the bugfix
mentioned below.
I am not quite sure whether I use BorderedNodeFigures or not. Where can I find this information? I
generated the diagram editor plugin using the dashboard. Transforming the gmfmap file to gmfgen file
and than generate the diagram editor. (Sorry for simple questions but I am new to use GMF)
Regards, Martin

Martin,
I guess a quick way to check is to search your generated code to see if
you have any EditParts that extend AbstractBorderedShapeEditPart. Or
put a breakpoint in the BorderedNodeFigure constructor and then open
your diagram.
Regards,
Linda

Linda,
I checked both ways described below and found nothing. So this means I did not use
BorderedNodeFigures and the below mentioned bugfix will not improve the performance. Right?
So I have to use a multi page editor to improve the performance. Or do u have another suggestion?
Regards, Martin

That's right.

No, I don't have any other suggestions. Splitting your diagram into
smaller pieces is likely your best course of action.

Sorry for this maybe heretic question: What is the point in having a
diagram with 10000 nodes, and even worse the same amount of connections?
That diagram will neither allow you to edit anything in a sensible
fashion, nor give you a valuable overview.
A diagram is a very human centric thing - as opposed to let's say a
table in a relational database. It should help us understand a complex
structure. No human being will ever have any benefit from a diagram that
is that huge. Your computer is fine without diagrams, and with flat
datastructures of 10000 and more elements.
Try to think about partitioning your model (scopes, namespaces,
packages) or nesting elements (refinement). Is it possible to have a
separate diagram for each scope? You can refine elements using the
"Related Diagram" feature in the map model, that generates an
OpenDiagramEditPolicy.
Sorry for being that direct. But I've been in too many projects were the
clients wanted huge posters rather than human readable diagrams. The
only purpose of these were to show others how complex a certain matter
is. In reality, the usual patterns of analysis, divide and conquer and
refinement were applied to govern the complexity. But that - of course -
was not reflected on the diagrams.
Regards
Jan
