MANY PAGES TUNING
The “Many Pages Scenario”, derived from the Base Portal Scenario, measures the effects of having larger numbers of pages visible to the users.
Since it is derived from the Base Portal Scenario, the same tuning that was used for the Base Portal Scenario applied for the Many Pages Scenario. The differences in tuning are mentioned below.
