Caches: LRU v. random
Read OriginalThis technical article analyzes and compares different CPU cache eviction policies, primarily Least Recently Used (LRU) and Random. It explores the performance of these policies, including a '2-random' variant, using SPEC CPU benchmark data across various cache sizes (L1, L2, L3). The analysis includes detailed miss rate ratios and discusses the trade-offs and performance characteristics of each policy in hierarchical cache systems.
