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.
