WitrynaIf we can clearly see access patterns and can predict future required pages, then 'optimal page replacement' is the best. As mentioned by sanjay in the other answer, it minimizes page faults. If the pattern cannot be predicted, LRU could be decent for most of the real-world workloads. But some work-load may show FIFO outperforming LRU. Witryna6 mar 2012 · This has the advantage of allowing you to replace the underlying concrete class with any class that provides the Queue interface, without having to change the code too much. The basic changes are to change the type of fifo to a Queue and to use remove() instead of removeFirst(), the latter being unavailable for the Queue interface.
