The performance of diagrams with ~100 objects is very low (and it’s not PC performance issue).
Can you share any tricks to tune VP or JRE?
VP is my main tool so I can accept JRE config tailored especialy for VP.
There are couple of reasons could lead to performance issue, e.g. size of the diagram itself (number of elements & connectors), how model elements being organized in project, memory setting, etc… The articles below provide some help on this topic. Hope this can help to your case.
I came to this topic after I had reverse engineered several large Java modules into my model, after which, editing diagrams had become very slow and tedious. Even selecting a shape in a small diagram exhibited delays of up to 20 seconds. For anyone who may have similar issues, I can verify that one of the suggestions given here by Rain really helped me.
Although most of the imported objects were in a nested Model, the data entities, (about 100), that were imported were all at the root level. I created a new Model and moved those entities into it, saved the file and restarted VP. That seems to have done the trick. I can now edit diagrams without any noticeable delay.
