Research On The Optimization Technology Of The Front-end Performance Of Web System Based On Bootstrap

With the rapid development of Internet and computer technology,Web application has become an indispensable tool in people's daily life.In order to meet people's needs,Web system business is becoming more and more complex,in this case,the Web site performance requirements are also increasing.For optimizing the performance of Web,background optimization technology has been very mature,but the single use of background optimization technology has been unable to meet people's needs,in order to improve the performance of the Web site,improve the user experience,more and more people began to study Web front-end optimization technology.In this paper,we focus on the research of the optimization technology of the front end of the Web system,and the main contents of the research are concluded as follows:1?This paper firstly summarizes the development of Web system and the contents of Web front end.Secondly,the working principle and working mechanism of HTTP technology are discussed.Finally,the paper analyzes the factors that affect the performance of Web front end,summarizes the Web front-end optimization technology and introduces the Bootstrap front-end framework and its advantages.2?For the problem of low resource restriction of browser concurrency,a new scheduling algorithm is proposed,which considers the time and document to be two indexes,and designs a kind of concurrent request scheduling weight model.Experiments show that compared with the none optimized web pages,using the optimization algorithm to optimize the web page can effectively reduce the document download time and document rendering start time.3?In order to solve the problem of the localStorage access performance overhead and the upper bound of localStorage storage space,a new localStorage scheme is proposed.Experiments show that this scheme can improve the storage performance and avoid the storage of the data.
