Research And Practice On Web System Performance Optimization Related Technologies

Web systems have become more functional and interactive as web technology advances and web users increase.These systems need to meet user performance expectations while dealing with complex user interactions and requirements.However,many conventional web systems face problems such as page delays,slow home page loading,and high resource consumption,which degrade the user experience.Furthermore,conventional web systems also struggle with code modularity,reuse,and maintenance issues.Therefore,it is important to optimize the performance of web systems for practical purposes.In order to improve the user experience of the Web system and reduce the development and maintenance costs of the Web system,this paper optimizes the performance of the Web system from two aspects: cache optimization and front-end optimization,and uses the component technology to improve the development efficiency of the Web system.The main research work of this paper is as follows:(1)This paper proposes an adaptive cache optimization method based on TTL(time to live)that considers the differences in update frequency and access frequency of web resources.This method dynamically adjusts the cache time according to user real-time access volume and resource characteristics,ensuring cache data consistency and cache hit rate;And improves the cache update method,allowing only invalid cache data to be updated when accessed for the first time,to prevent cache breakdown issues.The experimental results in this paper show that this method can better improve cache hit rate while ensuring cache data consistency,while minimizing performance impact when cache fails compared to some existing cache methods.(2)This paper proposes a front-end optimization method that considers the impact of web page resource size and request number on network response time.This method uses resource compression,image integration,and delayed loading to reduce web page resource transmission volume and request number,speed up web page loading,and improve user experience.The experimental results in a real system show that compared to previous optimization,this method can significantly reduce web resource size and resource request number,and increase web page overall loading speed by more than 35%.(3)Aiming at the problems of high development cost and low efficiency of Web system,using software reuse and component-based development methods,based on the open source framework,a Web system with high performance,low coupling,easy expansion and easy maintenance is built,which reduces the difficulty of system development and maintenance costs,and improves the development efficiency and system reliability.
