How can I optimize the performance of an LRU cache?

How can I optimize the performance of an LRU cache?

To optimize an LRU cache, consider adjusting the cache size, using efficient data structures, and minimizing cache misses.

What data structures are best for implementing an LRU cache?

A combination of a hash map and a doubly linked list is often used for efficient LRU cache implementation.

How do I measure the performance of my LRU cache?

You can measure performance by tracking hit/miss ratios, access times, and memory usage during operations.

Are there any common pitfalls to avoid when using an LRU cache?

Yes, avoid using a cache size that is too small, which can lead to excessive evictions, and ensure thread safety if accessed concurrently.
