Composite Applications Best Practices
∙ Another area to consider regarding teamspace complexity is the number of application roles. For many teamspaces, two roles manager and user are adequate. Don’t create additional roles unless they are really needed

WEBSPHERE PORTAL CACHES
General Information
enabled The enabled property determines whether a cache is used or not. If a cache is not enabled, the property has a value of false, then no values are held by the cache and every cache lookup will return a null value. This property should only be modified for testing purposes, never in a production environment. The supported values are true and false and the global default value is true
Supported values are true and false. The default values shipped in WebSphere Portal V6.1 should apply to most configurations. If you do not have a cluster there may be a small performance benefit to setting this property to false since a different cache implementation is used. We did not modify the defaults in our single node measurement environments
