ABSTRACT:
The present invention provides a method and apparatus for measuring performance of a computer system. The method includes generating a first setpoint, generating an event, timing at least a portion of the event, comparing the timed portion of the event with the first setpoint, and producing an indication of undesirable performance in response to the timed portion of the event being greater than the first setpoint. The apparatus includes a storage unit adapted to store a user perception tool, and a control unit adapted to execute the user perception tool, wherein the user perception tool causes the control unit to measure latency of a computer system and infer from the latency a user perception of performance.
