I have a reasonably large assembly file that takes about 8 minutes to load.  I assume most of this load time is due to the majority of the files being fully resolved, but I opened the assembly in large assembly mode and my system settings are set to automatically load components lightweight.  Right clicking on the assembly in the feature tree only offers the option to "set lightweight to resolved" which leads me to believe everything that can be lightweight is.  What could cause so many components to have to be resolved for the assembly to load?
