A performance issue occurs when you expand the Network view in SAS Visual Investigator. The tool seems to take a long time to write the node results. This issue persists even after the server takes all of the possible measures to improve performance. 

The back-end returns all the data to the frontend within a few seconds, but the frontend keeps processing this information for a long time. An investigation determined that there are simply too many nodes being loaded into the Network view at one time. The problem is actually the amount of time that the JavaScript takes to render the components on screen. 

There is no workaround for this issue. 

The SAS^® Visual Investigator 10.8 Hot Fix 16 will improve the frontend process responsible for rendering the components on screen.
