The invention discloses a computer software performance testing method, comprising the following steps: S1, turning on the computer, taking the software to be tested as the first opening object, and then clicking on the opening software to record the response time of the software; 2, taking that software to be tested as a second open object, and then clicking on the software to open the software,recording the response time of the software, comparing the response times of the two times, and obtaining the response time of the software under the conditions of different running memories; S3: turning on the computer, recording the current CPU utilization rate of the computer, then turning on the software to be tested, recording the CPU utilization rate at this time, and calculating the CPU utilization rate of the software to be tested. The invention can combine the response time of the software to be tested under different running memory conditions and different temperatures, and combine the CPU utilization rate of the software to be tested and different software to synthetically analyze and obtain the performance of the computer software, the performance test is more comprehensive, and the performance of the software can be well reflected.
