MRU (Most Recently Used) Cache Visualizer

Visualize MRU cache replacement and see how evicting the most recently used item outperforms LRU on cyclic workloads.

MRU Cache: how it works

What is MRU?
Most Recently Used evicts the item that was accessed most recently. Counter-intuitive, but useful when the latest access is the least likely to repeat.
When to use
Sequential file scans, media streaming, or any workload where you cycle through data once. After reading a page, you won't read it again for a long time.
LRU vs MRU
On the same sequence, MRU often outperforms LRU on cyclic workloads. The animation shows hit-rate differences between both policies side-by-side.
