Spectrum locked up for a couple minutes when I was moving 9 Network models from new Devices to Universe at the same time.
When a Topology model (Network or LAN for example)is cut and pasted into a new Topology, the Topology model that is cut and pasted along with the models container within the Topology model and their child models have a number of their current associations removes and then new associations created. There can be thousands of associations involved. If so, this can take time to complete.
Release : Any
Component : Spectrum Discovery/Modeling
Copy fewer models at the same time.
