QE: This was opened a couple months ago. Please retest on latest build. Using 256 as my mx setting, I am getting diagram creation in under 5 seconds. If still an issue, reopen.
According last data from Performance dashboard Creating empty UML diagram takes 6377 ms on Linux Ubuntu and 6784 ms on Windows XP on recomended configuration machines.
Did some profiling but not sure what can be tidied up to make it run faster. Attached is a screenshot of the profile session.

i compared a 5.5 and couple of 6.0 builds, as of 08/29 and 09/13. There isn't visually noticeable difference, less mentioned above 2-3 sec. to 10-15 sec or 1.2 vs. 12 sec mentioned here http://jupiter.czech.sun.com/wiki/view/PerformanceQE/UMLPackPerformance On my specific laptop (2.33 Centrino Duo it took about 3-4 sec. for both cases - 5.5 and 6.0) Please provide specific reproducible scenario or instructions or links to instructions on how to/where from to run the automated test. Also, last comment from Rashid makes it look like the bug is about absolute value on recommended config, though originally it was filed about regression. Please clarify.
now i see the problem - when the diagram is created and thus new node is added into the folder with many existing nodes (like default package of jEdit model - 200+ nodes) the delay is noticeable. It is also happens to any new element - "new class" for example. The reason is linear search through the node set in openide/nodes that is filed as IZ 116917
fixed as openide/nodes IZ 116917
