Big Data Intelligent Analysis Based Web Front-end Performance Optimization and Its Application Research

With the development of information technology, Web application systems are being used by more and more users. As the user base increases, the number of concurrent accesses continues to increase, leading to a decline in the quality of service of web systems. This paper will analyse the importance of web front-end performance optimisation of big data intelligent analysis to the whole system, and introduce the optimisation model of web front-end performance based on big data intelligent analysis. The specific application strategies after web front-end performance optimisation are explained in terms of request-related optimisation, HTML structure optimisation and page JavaScript optimisation, which can further improve the user experience.
