Evicting the most-recently used (MRU) page does very well on LRU's worst case. In general, however, MRU is a bad idea, since many programs exhibit temporal locality in their memory accesses, and MRU is effectively assuming that memory accesses will not exhibit locality.Another possibility is First-In, First-Out, or FIFO. At ?rst, this seems like it would be competitive with LRU, but it is not, since it also ignores temporal locality. For example, with a cache size of three, and the access pattern ABCAD, A would be evicted when D is loaded into the cache, which generally is not a good idea. (FIFO also has an unusual property called Belady's Anomaly in which for contrived examples, means that adding more memory to a system can cause more paging. So adding more physical memory to a computer using FIFO replacement could in theory make it slower. This cannot happen with LRU replacement.
The term ‘page traffic’ explains Page traffic’ explains the movement of pages in and out of memory.
