Inappropriate Situations High Data Rates Do not use certified message delivery in situations that require high data rates. In comparison with reliable delivery, certified delivery requires additional processing time, exchanges more control messages, and consumes more process memory (and optionally disk storage as well). Usage of these resources grows in proportion to three quantities: • The number of certified messages sent. • The size of the data in those messages. • The number of listeners that receive certified delivery. Therefore, for optimal performance, we encourage sparing use of certified message delivery.
