Benchmarking Distributed Caches: Memcache, Redis, Valkey, Dragonfly, and Garnet
2025-07-15
This study performs a comprehensive benchmark of five distributed caches: Memcache, Redis, Valkey, Dragonfly, and Garnet. Metrics include throughput, latency, and CPU cycles. The testing environment uses an AWS c8g.8xlarge instance and the memtier_benchmark tool, varying pipeline sizes (1, 10, 25, 50). Results reveal performance differences across various metrics, aiding developers in selecting the optimal cache for their application needs. The two-week long benchmark included 15,000 individual runs.
