Performance Factors in ASP.NET Web Applications with Limited Queue Models

Distributed systems and Web applications play an important role in computer science nowadays. The most common consideration is performance, because these systems must provide services with low response time, high availability, and certain throughput level. The performance of a Web application is affected by several factors. The goal of our work is to analyze how some of them affect the response time. In this paper, the effects of two configurable settings of the ASP.NET application server are discussed: the limit of the global queue and the limit of the application queue. The response time of a test Web application are measured, while changing these settings. The results are analyzed in a qualitative manner which is followed by using statistical methods: independence tests to investigate which factors influence principally the performance. Our experiments have shown that the global queue limit and the application queue limit are performance factors. Finally, optimal settings according to the performance-related requirements are determined as a function of client workload and the settings of the thread pool attributes
