Cache Working-Set Simulator

Push a skewed stream through LRU/LFU/ARC and read hit rate against cache size.

What hit rate does this LRU hold under Zipf traffic?

Working set exceeds RAM — expect compulsory misses.

Method

  • Deterministic local model of the mechanism — knobs recompute outputs instantly with no network.
  • Numbers are teaching approximations, not production capacity guarantees.
