Abstract
With the rapid development of Internet technology, Web servers are facing increasing pressure of concurrent access, and performance optimization has become the key to improving service quality and user experience. This study focuses on the Web server performance optimization in the Linux environment, aiming to improve the server processing capacity, response speed and resource utilization through systematic technical means. Based on Apache and Njinx, the paper is analyzed from hardware configuration, operating system parameter adjustment, network protocol optimization, and application layer configuration. The scheme of combining dynamic load balancing algorithm and caching mechanism is innovatively introduced. Through experiment, this scheme can effectively reduce the server response time by more than 20%, and control the CPU utilization rate within a reasonable range. At the same time, the Linux kernel parameters are deeply optimized, especially the refined configuration of TCP / IP stack related parameters, which significantly improves the network transmission efficiency.
