    Performance Evaluation is essential to that the web applications are providing a satisfactory level of service to its users in terms of scalability, stability, and throughput or response time. Web application performance evaluation process includes experimental designing, generating workloads for experiments, executing test while monitoring resource utilization of server and client, and representing results after test execution. This paper analyzes a number of popular performance evaluation tools in terms of how w ell they contribute to this complete process of evaluation. The results show that majority of the existing tools for web application performance evaluation have several limitations as far as the entire testing process is concerned, for example experimental design and resource monitoring do not co-exist in a single tool. Our contribution is to develop a fully fledged, open source tool which we name as WingPerf. It facilitates the entire web application performance evaluation process. This paper also presents the architecture and the functionalities of WingPerf.
