What are performance cache algorithms and how do they work?

Performance cache algorithms are techniques used to store frequently accessed data in a cache to speed up retrieval. They optimize the use of memory and reduce latency.

Can you explain some common types of cache algorithms?

Sure! Some common cache algorithms include Least Recently Used (LRU), First In First Out (FIFO), and Least Frequently Used (LFU). Each has its own method for deciding which data to evict from the cache.

How does the LRU algorithm decide what to remove from the cache?

The LRU algorithm removes the least recently accessed item from the cache when it needs to make space for new data. It keeps track of the order of access to determine which item is the oldest.

What are the advantages of using cache algorithms?

Cache algorithms improve performance by reducing access time for frequently used data, lowering latency, and decreasing the load on primary storage.
