We’re using bpmn.io on IE11, with Camunda as back-end, and we noticed that parsing the XML is slow when the BPMN contains many nodes. Is there a more concise representation that can be used between Camunda and bpmn.io? (e.g. json or compact binary format)
No, there isn’t. I also doubt that importing diagrams represented as JSON would be much faster. What’s actually slow is rendering the diagram, not parsing the XML.
