Research on Web Front-end Performance Optimization Based on XML

As for the optimization of Web sites, the optimization technology in the background is mature, but the research and attention on the performance optimization of Web front-end is far from enough. Based on XML, this paper first analyzes the research status from the research background of Web front-end performance optimization. Then, the principles of request response mechanism, HTTP protocol analysis, browser response mechanism and the particularity of mobile Web front-end are analyzed. According to the research and analysis of front-end related theories and the experience of engineering practice, a series of optimization schemes are put forward from the aspects of page composition, picture and Web cache. Finally, a comprehensive experimental test is carried out by combining theory with practice, which verifies the positive influence of the optimization scheme on the performance optimization of Web front-end.
