On pseudo workload for performance measurement of interactive systems
A workload problem in performance evaluation of interactive systems is discussed. A simple method to create a pseudo workload usually called a synthetic job is proposed. A pseudo workload can be generated by using two functions. One of these functions is to execute deferred jobs in a time-sharing environment, and another one is to place a program being executed into waiting status during a required time.
A detail process to generate the pseudo workload using the functions such as deferred processing and the waiting function is shown. Appropriateness of the pseudo workload is discussed. Finally, several examples of performance measurement under the pseudo workload operation are given.
