Abstract

The performance of a web application is affected by several factors. In this paper, the effects of two configurable software settings of J2EE application servers are discussed: the maximum size of the thread pool and the maximum size of the connection queue. Previous work has shown that both tuning parameters have a considerable impact on the performance metrics, and both of them should be taken into account when constructing a performance model of a web application. This paper presents a queueing network-based performance model that is able to capture the effect of the connection queue limit. New performance measurements which can help improving this model are also presented.
