What are the best practices for disk cache usage?

To optimize disk cache usage, consider the following best practices: 1. Use appropriate cache sizes based on workload. 2. Implement cache eviction policies like LRU (Least Recently Used). 3. Monitor cache performance regularly. 4. Use caching for frequently accessed data.

How do I determine the right cache size for my application?

The right cache size depends on your application's data access patterns. Analyze the working set size, which is the amount of data frequently accessed, and set your cache size accordingly. A good starting point is to cache around 20-30% of the working set.

What are some common cache eviction policies?

Common cache eviction policies include: 1. LRU (Least Recently Used) - removes the least recently accessed items. 2. FIFO (First In, First Out) - removes the oldest items. 3. LFU (Least Frequently Used) - removes items that are least frequently accessed.

How can I monitor cache performance effectively?

You can monitor cache performance by tracking metrics such as hit rate, miss rate, and eviction rate. Tools like Prometheus or Grafana can help visualize these metrics and provide insights into cache efficiency.
