ArcMap is, unfortunately, very linear/serial in many aspects, including rendering and refreshing data layers. If you have several data sources that each take several seconds to refresh, it can easily cause ArcMap to "hang" for 10+ seconds or even much longer. We have run into similar issues in our organization where users have 50+ data sources from EGDBs, GIS Servers, and other network sources in a data frame and complain about how long it takes to open ArcMap and visualize data.
