What are the drawbacks of LRU caching?
LRU caching can lead to high overhead in terms of memory usage and can be inefficient for certain access patterns.
Can you explain why it might be inefficient?
Sure! LRU can perform poorly if the data access pattern is not temporal, meaning if data is accessed in a way that doesn't fit the LRU model.
Are there any specific scenarios where LRU caching fails?
Yes, for example, in cases of 'cache thrashing' where the working set size exceeds the cache size, LRU can continuously evict useful data.
What are some alternatives to LRU caching?
Alternatives include LFU (Least Frequently Used), FIFO (First In First Out), and ARC (Adaptive Replacement Cache), each with its own pros and cons.
