Research on Performance Optimization of Web Application System based on JAVA EE

Abstract

With the development of informatization, the Web application system is being used by more and more enterprises and institutions. With the increase of the user group, the concurrent visits are increasing, which leads to the poor service quality of Web system. Several high-concurrency solutions existed, but they address only one aspect of the performance problem, and small and medium enterprises need to consider the cost. This paper will analyze the performance factors affecting the Web application system through multiple levels, aiming to build a Web application system with high availability, high concurrency, high expansion and less cost. Based on the factors affecting the performance of the Web application system, the project of the online mall system was optimized, and the service support of the Web application system was adjusted to make it more suitable for the system requirements. Besides, related SQL statements were optimized, Java code layer was optimized, user experience layer was optimized, and performance testing and analysis were completed.
