Core Data is just passing the query off to the database. I'm not sure why you think going to the database directly will do anything for the 179.9 / 180.0 seconds it takes to evaluate the query in the database.
I suspect that he wants a background thread that simply sits and passes results back to main thread directly from sqlite3_step(). I don't know of a way to incrementally return results in CoreData when the query is very expensive; using setOffset will re-issue the query and even fetching just IDs still has to wait for the entire query to finish before return any results.
