Zusammenfassung:	PROBLEM TO BE SOLVED: To facilitate performance analysis of multithreaded programs executed in data processing systems.SOLUTION: The invention includes: a step 310 of executing an application program using such a plurality of threads that each thread makes transition among a plurality of states; a step 315 of reading data corresponding to characteristics regarding prescribed performance of the application program for the plurality of states of each thread during a measurement period; and a step 320 of displaying an image which has a graph of each thread reflecting the measurement period, performance levels corresponding to characteristics regarding the prescribed performance of the application program, and a change in performance at each time point in each state.
