WitrynaRandom Random: Pick a random page for every replacement. Unpredictable and hard to make any guarantees. TLBs are typically implemented with this policy. FIFO First In, First Out: Selects the oldest page to be replaced. It is fair, but suboptimal because it throws out heavily used pages instead of infrequently used pages. MIN Minimum: … Witryna7 gru 2015 · 1. @seeker Yes, this answer mixes terms (the second sentence should read most frequently used things) and uses MFU cache to mean a cache with a LFU replacement algorithm. In my experience, this is the incorrect term. LRU cache refers to a cache that evicts the least recently used item, so MFU cache should be a cache that …

FIFO Page Replacement Algorithm

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.
