Extending the Mean-Value Analysis Algorithm According to the Thread Pool Investigation

Web-based information systems play an important role in computer science. The most common consideration is performance. With the help of a proper performance model and evaluation algorithm, the performance metrics can be determined at the early stages of the development process. In our work, the response time and the throughput of multi-tier Web applications have been predicted based on a queueing model. The goal of our work is to extend the mean-value analysis (MVA) algorithm according to the investigation of the thread pool. The MVA and the proposed extended MVA evaluation algorithms have been implemented with the help of MATLAB. The input parameters have been estimated based on one measurement, and the model has been evaluated to predict performance metrics. Moreover, a Web application has been tested with concurrent user sessions in order to validate the proposed algorithm in ASP.NET environment.
