ONJava.com: Software Infrastructure Bottlenecks in J2EE: "Scalability is one of the most important non-functional requirements of a system. But there could be several bottlenecks within a system, which might prevent it from being scalable. In this article, we try to analyze the case in which the software infrastructure becomes a bottleneck, long before any of the hardware resources (such as CPU, memory, disk space, and network speed) are fully consumed. This is a tricky problem whose solution is explored below. "
