A method of generating massive virtual clients and model-based performance test

Testing the performance of a server that handles massive connections requires to generate massive virtual client connections and to model realistic traffic. In this paper, we propose a novel approach to generate massive virtual clients and realistic traffic. Our approach exploits the Windows I/O completion port (IOCP), which is the Windows NT operating system support for developing a scalable, high throughput server, and model-based testing scenarios. We describe implementation details of the proposed approach. Through analysis and experiments, we prove that the proposed method can predict and evaluate performance data more accurately in cost-effective way.
