You can then use methods of this utility class to retrieve various performance information about the message that you have just received.
When these metrics are enabled an instance of this class should be created from a response, acknowledgement, or message handler using code such as below:
var mpiutil:MessagePerformanceUtils = new MessagePerformanceUtils(event.message);
