Two closely linked optimisations: eagerly load foreign key properties by default, but only with the identity property specified for eager loading; when loading models in only their identity version, don't do a
database query and construct the model directly by the ID given. Together they shave approx 15-20% off our ingestion tasks in preliminary measurements
