What are the differences between LRU and other caching algorithms?

What are the differences between LRU and other caching algorithms?

LRU, or Least Recently Used, evicts the least recently accessed items. Other algorithms like FIFO and LFU have different strategies.

Can you explain how FIFO works compared to LRU?

FIFO, or First In First Out, removes the oldest item in the cache, regardless of how often it was accessed, unlike LRU.

Which algorithm is more efficient in terms of performance?

It depends on the use case. LRU is often better for workloads with temporal locality, while FIFO can be simpler and faster in some scenarios.

Are there any situations where LRU performs poorly?

Yes, LRU can perform poorly in cases of frequent access patterns that cycle through a set of items, leading to thrashing.
