Abstract


With the popularity of high - speed mobile networks , as well as the rapid development of the hardware , a growing number of mobile devices with networking capabilities. The main way people use mobile Internet browser is a mobile terminal access websites , order processing data anytime, anywhere access to or release information . Access the Web page on a mobile terminal , slower to open a serious impact on the mobile user 's Internet experience . Accelerate the page open mobile terminal speed to enrich the experience of mobile Internet users , has important practical significance . The Render Tree structure of the mobile terminal cache is optimized processing speed into the design and implementation of mobile terminal page open . The paper first introduces the cached content in the mobile terminal , and a brief analysis of the mobile terminal potential cache content , the basis of the existing mobile terminal cache cache corresponding Web page Render tree structure . Then , considering the characteristics of mobile terminal ( main CPU processing power , low battery) and WebKit page to open the process to study how a mobile terminal cache Render tree structure generated during the corresponding Web page Render tree structure : WebKit page opens optimized processing - clipped the leaf nodes RenderText and similar nodes to merge , given a specific algorithm . Then WebKit corresponding Web page creation process of the Render Tree structure and Render Tree nodes cache reuse in mobile terminal and the overall structure of algorithm . Finally , based on the above study , modify the WebKit core WebCore code implements the algorithm proposed in this paper ; modify the the browser software source code MeeGo system , Tablet PC cache optimized Render tree structure and reuse cache Render tree structure . Related test , do a brief analysis of the testing results .
