This section provides a summary of the caching strategy used.
“Cached (LRU) Buffers” reports the total number of buffers placed at the head of the most-recently used and last-recently used (MRU, LRU) chain in all caches.
“Discarded (MRU) Buffers” reports the total number of buffers in all caches following the fetch-and-discard strategy—the buffers placed at the wash marker.
