We increased the sizes of the following caches in our measurement environments so that all frequently-accessed pages, which depend on our scenario, can be cached.

com.ibm.wps.datastore.pageinstance.OIDCache

com.ibm.wps.datastore.pageinstance.DerivationCache

com.ibm.wps.model.factory.ContentModelCache

com.ibm.wps.model.factory.NavigationSelectionModelCache

com.ibm.wps.ac.PermissionCollectionCache

com.ibm.wps.ac.ProtectedResourceCache

com.ibm.wps.ac.ExplicitEntitlementsCache.USER_GROUP

com.ibm.wps.datastore.services.Identification. SerializedOidString

We increased the lifetimes of all caches to at least one hour.
