From the docs:

"The FastObservableCollection does not raise events for every item, but only invokes events for the complete range of items added to or removed from the collection.

When modifying a large collection of items, it is not required to raise change events for each added / removed value. Therefore the FastObservableCollection will disable change notifications until the full collection modification is done and then raise the change events just once."
