Performance testing: Analyzing differences of response time between performance testing tools

This research focuses on the study and evaluation of response time differences given by three tools used for performance testing. The motivation for this research work is to understand the behavior of various performance testing tools towards determining the accuracy of the response time result. It is conducted with the aim of demonstrating and proving that differences of response time do exist between different tools when conducting performance test for the same webpage as well as analyzing the reasons behind that situation. A static HTML webpage is put under load test for 1, 100, 200, 300, 400 and 500 concurrent users performed by the three tools. The findings clearly showed that different performance testing tool gave different response time when conducting load testing on same webpage. The findings are also supported with the justification for these differences, which involve architecture and simulation mechanism of the respective tool. The summary and future work is presented at the end of the research.
