[Abstract]:With the popularization of EPG (Electronic Program Guide) system, the requirement of its performance is becoming higher and higher. The software and hardware bottleneck of EPG system can be found quickly by using automated test tools, and the cycle of system testing, optimization and release can be shortened effectively. Improve software development efficiency and software quality. Therefore, how to effectively improve and optimize the performance of EPG system is an urgent problem to be solved. The performance problem is the key problem in the further development of EPG system. At present, there are two main difficulties in the research of EPG system performance test. On the one hand, it is the integrity, robustness, stability, accuracy of the system processing data; on the other hand, it is the page response speed of the EPG server when the multi-user simultaneously uses it. Based on this, aiming at the complex performance test of EPG system and the high difficulty of multi-user load simulation, the test scheme of existing EPG system is optimized by using Loadrunner in real-time, stability and fault tolerance. The access efficiency of MySQL and other databases is optimized to achieve the effect that the server still runs stably after increasing the number of page views. The main work of this paper is as follows: (1) the software testing theory is studied, the specific flow of EPG system performance testing is analyzed, and the advantages and disadvantages of Loadrunner, an industrial standard load testing tool, are deeply analyzed. (2) to test the performance of EPG system with automatic test tools, and analyze the test results, find out the key factors that affect the performance of EPG system, and put forward the optimization scheme to optimize the front page and MySQL of the system. The reliability of the optimized scheme is verified by the test results. (3) finally, a performance test scheme for EPG system based on Loadrunner is designed, and the system is designed and implemented, which provides an example for the subsequent performance testing of EPG system. Through the research of EPG system performance test and optimization method, Loadrunner tool is used to determine the performance bottleneck of EPG system, which provides an effective test method and optimization scheme for set-top box Web application performance test. The research innovation is to design a kind of overall performance test scheme in EPG system, and the validity of the test scheme is verified by the actual project, which achieves the initial goal of the paper.
