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. Witryna24 maj 2024 · The policy of LRU page replacement is frequently utilized as a page-replacement algorithm and is viewed as acceptable.
