Version 6.1 Guides
IBM WebSphere Portal Version 6.1 Tuning Guide
Abstract: Tuning and capacity are affected by many factors, including the workload scenario and the performance measurement environment. For tuning, the objective of this paper is not to recommend that you use the values we used when measuring our scenarios, but to make you aware of those parameters used in our configuration. When tuning your individual systems, it is important to begin with a baseline, monitor the performance metrics to determine if any parameters should be changed and, when a change is made, monitor the performance metrics to determine the effectiveness of the change.
IBM WebSphere Portal Performance Troubleshooting Guide

Monitoring performance in a WebSphere Portal environment
Abstract: This article introduces the various ways that you can monitor performance in an IBM® Websphere® Portal environment. These monitoring methods are useful in situations where a portal-based application is experiencing poor performance, such as slow loading pages, sporadic problems, or stability issues. The article looks at areas such as caching, JVM monitoring, database analysis, logging, and debugging to aid in monitoring and measuring performance.
IBM WebSphere Portal: Performance testing and analysis
Abstract: This article provides advice and methods for finding and resolving common performance problems with IBM® WebSphere® Portal. The WebSphere Portal SEAL team engages with high-profile customers experiencing significant problems with their WebSphere Portal deployments. In roughly 50 percent of these engagements, the major complaint is performance related. The task usually becomes one of finding and resolving these performance issues, often after the system has already been put into production.
IBM WebSphere Developer Technical Journal: Performance considerations for custom portal code
Abstract: Performance is often a trade-off between functionality, maintainability, program execution time, and memory consumption. This document offers programming advice for maximizing the performance of portal application components, such as portlets, themes, and skins, with IBM® WebSphere® Portal.
