How many products are in the room?
Shared rooms do a lot more auth checks, since there are multiple owners. The more products that are in the room, the longer it takes to load. Doesn't matter the size of the products.
The bug is so well known, that there's a name for it, "Chubby Room Bug", and people call shared rooms with lots of products "Chubby Rooms".
Once a shared room reaches like 50 or 100 products ... I think that's when people start calling it "Chubby", because the load times reach unbearable waits.
