Sun Java System Portal Server 7.1 Deployment Planning Guide

Portal Desktop Configuration

Portal Desktop configuration explicitly determines the amount of data held in memory on a per-session basis.

The more channels on the Portal Desktop, the bigger data session size, and the less the throughput of Portal Server.

Another factor is how much interactivity the Portal Desktop offers. For example, channel clicks can generate load on Portal Server or on some other external server. If channel selections generate load on Portal Server, a higher user activity profile and higher CPU overhead occur on the node that hosts the Portal Desktop than on a node that hosts some other external server.
