Memory performance prediction of web server applications based on grey system theory

With the success of internet, recently more and more companies start to run web-based business. While running e-business sites, many companies have encountered unexpected degeneration of their web server applications performance, which may lead to loss of customers. Many managers wish to have a decision-support tool that cancan answer such questions, such as will my web server applications performance degenerate?, and what are the main reasons of the degenerations?. In this paper we first propose a new memory performance prediction model of web server applications based on grey system theory. And then, a software system Memory Performance Manager (MPM) is developed for predicting memory performance of the web server applications. Massive experiments demonstrate that the effectiveness of MPMs in predicting web server memory performances
