Research And Application Of Web Caching Technology Based On Memcached

With the rapid development of Internet and the strong support of the state to "Internet +", all traditional industries are Springing up. In the fierce competition in the Internet industry, people have more and more requirements on the function and design of the software system, especially the performance of the system. Web site performance is good, the user access delay is small, has become a long-term development of the site’s core competitiveness.This thesis is based on the "Internet +" environment. It is a preschool education integrated management information platform based on J2 EE platform, using is the current mainstream SSH framework, is a typical J2 EE three-tier structure, suitable for the needs of the system fast and agile development. With the development of the project business and the continuous improvement of the various functional modules, the amount of users and user information is also greatly increased. In the development of the requirements of the design, but also to consider the performance of the system. From the perspective of system stability and user experience, through the application of caching technology in this system, it can effectively improve the system performance, reduce user access to the Web site delay, is conducive to improve the user experience.Firstly, the thesis introduces the development trend and current situation of Web caching schemes, and then introduces the application of Web caching technology in the system, and then describes the basic principle of Memcached caching technology. In the analysis of the preschool education information integrated management platform performance status. It is pointed out that where needs to be improved, and aiming at these problems, this thesis introduces the detailed cache policy formulation, and Memcached in project application. According to the test plan, the test data and conclusion, that is, the application of appropriate caching scheme and Memcached caching technology can effectively improve the system performance, reduce the user access to the site delay, for saving the project cost, and business development and other side masks have practical significance.Currently in the a preschool information integrated management platform mainly the Caching Application Strategy and Memcached caching technology to improve the performance of the system, to achieve the following results:(1) database caching query results and reduce the user access delay;(2) to reduce the database access number database, lower load pressure;(3) enhanced scalability to meet future in business development needs.
