Method and computer program product for evaluating the performance of an object-oriented application program

A measure of the performance of an object-oriented application program is obtained by measuring, for a plurality of the user input functions of the application program for which a response is provided by the application program, an elapsed time between the initiation of the user input function and the response provided thereto by the application program. The measured elapsed times for each user input function are summed, and then an average response time is obtained for the application program by dividing that sum by the number of user input functions sampled. The measure of performance of the application program may be normalized with respect to a Function Point index derived for the application program. Additionally, for application programs that operate upon a database, the measure of performance may be further normalized with respect to the size of the database.
