“Utilization” reports the percentage of searches using this cache as a percentage of searches across all caches.You can compare this value for each cache to determine if there are caches that are over- or under-utilized. If you decide that a cache is not well utilized, you can:
Change the cache bindings to balance utilization. For more information, see “Caches and object bindings”.
Resize the cache to correspond more appropriately to its utilization.
For more information, see the System Administration Guide.
