When saving a field with field values it's constantly deleting then re-creating them even if they don't change. It should check if a value exists in database, but doesn't in post. If that's the case then remove it from database. It should also check if value exists in POST, but not in database. If that's the case then add it to database. This prevents redundant delete all and save all everytime you save the field.
