Sun Java System Reference Configuration Series: Portal Service on Application Server Cluster

Performance Requirements

A portal service is an end-user service, and a fairly high level of performance (an acceptably short response time) is expected. The performance of Sun Java System Portal Server is generally measured by the response time of the standard channels that are available in the default desktop sample. The reference configuration is designed to provide a response time under two seconds for these channels at peak load levels. In a typical deployment, however, response time is dependent upon not only the portal service, but also the back-end applications that it aggregates.
