cacheinfo
Cacheinfo is a term used to describe information about the cache memory configuration of a computer system. It encompasses details about CPU caches at multiple levels (such as L1, L2, and L3), including cache type (data, instruction, or unified), size, associativity, line size, and how caches are shared among cores. Cacheinfo is used by operating systems, profiling tools, and performance-oriented software to understand and optimize cache utilization.
In Linux systems, cache topology is exposed through the sysfs hierarchy for each processor. The per-CPU cache
Cacheinfo is important for performance optimization because cache behavior heavily influences execution time. Developers use cacheinfo
