BPMN Modeler Performance Issues with Large Diagrams

Hello

I have been facing performance issues when working on large and complex BPMN diagrams in the Camunda Modeler (desktop version). Specifically; as the diagram grows with additional elements and connectors, the application starts to lag significantly, making tasks like dragging elements, zooming, or even selecting tasks quite slow. :innocent:

This happens despite running the Modeler on a high-performance machine with plenty of RAM and CPU resources.

Is there a recommended approach to optimize performance for such large diagrams? Would breaking the diagram into smaller sub-processes improve usability, and if so, how can this be done without disrupting the overall workflow design? :thinking:
I have checked Slow Rendering for big diagrams - Modeler - bpmn.io Forum java guide for reference .

I’m also curious if the web version of Camunda Modeler offers better handling for such cases or if there are plans to improve the desktop application’s performance for large-scale BPMN files. Any tips or insights would be appreciated! :slightly_smiling_face:

Thank you !
