Sun Java System Portal Server 7.2 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 inter-activity 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.
