This technote contains links to additional reading on the topic of IBM WebSphere Portal Performance
This tuning guide provides details about the parameters that you can tune to improve portal performance. This guide serves as a very good starting point to start portal tuning process before production usage.
Performance tuning guide for WebSphere portal on IBM i
This document discusses additional performance tuning recommendations that is specific to running WebSphere Portal on the IBM i platform. The focus is more on platform level recommendations unique to the IBM i and are minimally discussed in the above guide.
Monitoring Performance in a WebSphere Portal environment
To tune your WebSphere Portal environment for optimal performance, you need to know what needs tuning. The monitoring methods discussed in this article cover several key areas of WebSphere Portal. They help you to view the true behavior of your WebSphere Portal environment and ultimately identify bottlenecks and potential problems. This article is meant to be an overview of monitoring methods rather than an in-depth look at any specific methods.
IBM WebSphere Portal performance testing and analysis
Finding and fixing performance problems in a production environment is challenging on a number of levels. Optimally, most bottlenecks in the system should be found and fixed before the system is allowed into production. This article explains a tested process that can ensure that, with high probability, most of the significant performance issues are found and addressed before you promote a system to production.
