What are the limitations of LRU caching?

What are the limitations of LRU caching?

LRU caching can be limited by its overhead in maintaining the order of items, which can slow down performance.

Are there scenarios where LRU caching is not effective?

Yes, LRU may not be effective in workloads with high variability or when access patterns are not predictable.

How does LRU compare to other caching strategies?

Compared to strategies like LFU or FIFO, LRU is generally better for temporal locality but can struggle with space efficiency.

What are some alternatives to LRU caching?

Alternatives include LFU (Least Frequently Used), FIFO (First In First Out), and ARC (Adaptive Replacement Cache).
