World Partition Streaming Performance Profiling

My large level with about 5000 actors per grid is using world partition and has some problems with certain grids loading which creates critical streaming problems. The actors in these grids don’t seem unremarkable from the other grids which stream in fine.
I am aware of the console commands wp.Runtime.** and have tried to use these to find the cause, however I require more information about the particular actors loading in from each grid so I can resolve which ones might have a critical streaming issue.
