The invention relates to an application program performance test control method and tool, and belongs to the field of computer program testing. The method is implemented by using an application program performance test control tool and comprises the following steps: test demand configuration data customized by a user is received and an application program to be tested is started; A test instruction for starting monitoring is received, then timing preparation is started, when the timing preparation reaches the monitoring preparation duration, a performance test script is called to perform performance monitoring and start monitoring timing, and when the monitoring timing reaches the monitoring duration, performance monitoring is paused, and a performance test report is generated; After the performance test report is generated, preparation timing is started again, when the preparation timing reaches the monitoring preparation duration, performance monitoring is continued, monitoring timing is started again, and when the monitoring timing reaches the monitoring duration, performance monitoring is paused, and the performance test report is generated; And the step is repeated until the number of times of monitoring the test requirement is completed.
