flex.messaging.messages.MessagePerformanceInfo
@exclude The MessagePerformanceInfo class is used to capture various metrics about the sizing and timing of a message sent from a client to the server and its response message, as well as pushed messages from the server to the client. A response message should have two instances of this class among its headers, headers[MPII] - info for the client to server message, headers[MPIO] - info for the response message from server to client. A pushed message will have an extra headers and its headers will represent, headers[MPII] - info for the client to server message poll message (non RTMP) headers[MPIO] - info for the pushed message from server to client, headers[MPIP] - info for the message from the client that caused the push message It has a symmetric AS counterpart - MessagePerformanceInfo.as
