When does FIFO win over LRU replacement algorithm?

WebMay 22, 2024 · LRU stands for Least Recently Used. The development of the LRU algorithm ended the debate and research that had been going on about page replacement algorithms in the 1960s and 1970s.

WebWe conducted a simulation study by varying the Grid Topology, Content Store, and Interest Rate size. Simulation results reveal that ARC replacement policy outperforms LRU replacement policy by achieving a 4% higher hit rate. We have also observed that ARC requires a smaller content store size than LRU to reach the 74% hit rate.

"WebA closer inspection reveals that LRU slightly outperforms FIFO and this is confirmed when we look at the raw data. For most runs (number of frames varied from 1 to 30), LRU produces fewer page faults. The optimal algorithm outperforms both and drops # page faults quite fast after 3 available frames, though it does begin to converge back at ... " - Fifo outperforms lru

WebJun 18, 2013 · However, FIFO outperforms LRU according to this technique. It is well known that input sequences for paging and several other problems show locality of reference [2, 3, 10, 13, 14, 49]. By definition, a sequence has locality if when a page is requested it is more likely to be requested in the near future. Therefore several models …
