User Activity

User activity is defined as the interaction that a portal users has with the portal server. It depends on the number of tabs, links, sites that a user has to go through to reach a specific channel or information.

User activity is also governed by the type of channels that a portal architect may decide to provide the users. For example, if the communications channels (default Mail and Calendar channels shipped with the Portal server software) are placed on a user's portal desktop, the user tends to demand updated content regularly. Such Portal sites with communication channels or connections to back-end systems face far shorter reload intervals . The affect of reloading the desktop is that it consumes CPU cycles and generates jvm heap garbage. Because portal is good at caching, sites that promote reloads can become memory bound before the CPU is stressed. It is recommended to use the JVM option for Concurrent garbage collector to alleviate this issue.
