It could be that there is no transaction block wrapped around the inserts (a BEGIN TRANSACTION before the start of the insert loop, and a COMMIT TRANSACTION at the end.) If there is no explicit transaction, then every insert has an implied transaction, which considerably slows down the database engine.
