Apparatus, methods, and other embodiments associated with reducing read starvation that is supported by a multi-purpose buffer managed by a least recently used (LRU) data structure are described. One example method includes changing how certain retired pages are added back into the LRU. The dual-purpose buffer may be used in data de-duplication to support satisfying ingest requests and to support satisfying read requests. The method may also include controlling the LRU to allocate active ingest pages and active read pages from the head of the LRU. The method may also include controlling the LRU to cause the active ingest page and the active read page to re-enter the LRU at the tail of the LRU. Unlike conventional approaches, the method may also include controlling the LRU to cause a retired ingest page to re-enter the LRU at a location other than the tail (e.g., head) of the LRU.
