LIRS

LIRS (Low Inter-reference Recency Set) is a caching algorithm designed to improve how computers manage stored data. It prioritizes keeping recently accessed items that are unlikely to be accessed again soon, while also retaining some older items that recently appeared frequently. By analyzing access patterns, LIRS distinguishes between data that is likely to be reused shortly and less relevant data, leading to more efficient use of cache space. This results in fewer misses (when needed data isn't in cache) and better overall performance, especially in workloads with complex or variable access patterns.
