What is the impact of cache replacement policies on system performance?
Cache replacement policies determine how data is managed in cache memory, affecting speed and efficiency.
Can you explain some common cache replacement policies?
Sure! Common policies include LRU (Least Recently Used), FIFO (First In, First Out), and LFU (Least Frequently Used).
How does LRU compare to FIFO in terms of performance?
LRU generally performs better than FIFO because it keeps frequently accessed data, reducing cache misses.
Are there scenarios where FIFO might be more effective?
Yes, FIFO can be simpler to implement and may perform well in workloads with predictable access patterns.
