I've followed all of the tips + tricks in the Basic Troubleshooting article but none of the info is really making a difference in system performance. We've recently began using shapes holding data and when ctrl c+v of a shape (or full diagram) there is severe lag on the document.
I have a simple task of duplicating diagram on page 1 on several additional pages and this task is quite literally taking me 3-4 hours. I know this is a known issue when using shape data but are there any tricks to minimizing the lag with this feature? It's painful.
