CacheBench is a benchmark and stress testing tool to evaluate cache performance with real hardware and real cache workloads. CacheBench takes in a configuration that describes the cache workload and the cache configuration and simulates the cache behavior by instantiating a CacheLib cache. It runs the workload and emits results periodically and at the end. The results include metrics such as hit rate, evictions, write rate to flash cache, latency, etc. The workload configs can be hand-written by a human, produced by a workload analyzer, or backed by raw production cachelib traces.
