Analysis and research on the performance optimization of Web application system in high concurrency environment

In high concurrency environment, the performance of Web application system cannot meet design or business requirements. This paper introduces system performance testing indicators, performance testing methods and performance optimization strategies. On this basis, according to the general system structure of high concurrency Web application system, the paper expounds the optimization scheme from three aspects: browser access, server and data storage. The validated results show that the response time of the system is shorten about 30%, and the concurrency number of the system is improved 4 times, the server resource utilization rate is improved 60%, and the system performance optimization achieves good results.
