摘要：
A method of measuring message response time performance of a data processing system includes the generation of timing messages when a data or status message is sent from a data terminal, such as a point of sale terminal in the system to a central processing unit, and when a data message is received at the terminal from the central processing unit. The timing messages include identification of type of message, time data taken from a timer in the terminal, and a sequence number which permits related messages to be paired so that the time values in each can be compared to determine a response time for the total period required for transmission of messages from the terminal to the central processing unit, any necessary data processing at the central processing unit and transmission of a message from the central processing unit back to the terminal.
