Is there a way to speed up the rendering for org charts that have dotted line managers enabled? We’re using on-prem Sp2013 user profiles with thousands of users and it takes a long time to initially render.
Thank you for your question.
Rendering depends on the structure, a browser and your PC performance.
How many levels do you display at onces? Did you try to enable caching in the General settings step of the configuation wizard? This would help to expand nodes faster for the second time within 24 hours. But if it is the first time, unfortunately, it will load the structure from scratch.
You may also use this JS code to store client side cache for different for a longer time:
renderer.config.clientSideCachingLifeMinutes = 4320;
