Optimization, Caching Technology-based Bbs Systems

With the increasing popularity of computer application, people's work and life more and more inseparable from the network. BBS as a traditional network applications, still attracts a lot of users, and subscribers range has been increasing trend. The concurrency value big, interaction, strong, information content high BBS system is different from general network application main characteristics. How to improve the BBS the response speed of system and is one of many researchers face of an important topic.Improve BBS response speed of a variety of ways, and all can be obtained a certain result. If can without any increase in hardware overhead situation inside short time improving website performance, then to the site owner:it's the most economical means. Web cache technology is in this imaginehow proposed by the most effective means. Based on an existing BBS website as an example, studies the cache technology in Web applications, and according to the test results, and proposes some opinions, which has certain reference value.This paper first introduced the Chinese Internet development status and the main problems facing Web system. Several methods to resolve to available are analyzed, by comparing their respective advantages and disadvantages, selected by the main contents-BBS cache technology application. Then it introduces cache technologies to produce such-distributes, application scope, cache the location and Web cache of several main performance indexes. Analyzes the static page and dynamic pages of cache sexual and cache position. Then according to the actual situation of the selected by asp.net 2.0 as the main technology platform, this paper describes the.net 2.0 provided during the cache management means and method of use. Based on analysis of existing systems, including BBS system user behavioral analysis and cache for qualitative analysis, and based on this advanced a system optimization scheme, including parameters of big changes in the page of a whole page caching, some of the content inside certain period with the stability of the page to part cache, needs a large number of inquiries operation can be generated page for application data cache. Also consider caching data expired, utilizing SQL cache rely on guarantee the data consistency. Finally, using the software of network monitoring function Firebug, optimizing before and after optimization system performance compared and evaluated. Conclusion, the integrated use of the proposed optimization scheme and overall system performance has greatly improved, reduced to user response of waiting time, improve the user experience.
