Dragonfly outperforms Valkey in throughput, performance stability, and memory efficiency, scaling linearly with CPU cores and excelling in high-concurrency, CPU-intensive workloads. Dragonfly's multi-threaded architecture allows it to scale nearly linearly with the number of vCPUs, combined with superior memory efficiency, making it a compelling choice for demanding in-memory data storage needs. In contrast, Valkey is bottlenecked by its main thread for CPU-intensive operations like ZADD, while Dragonfly demonstrates significantly greater memory efficiency and performs better under high concurrency. These benchmarks highlight the significant performance advantages of Dragonfly's architecture compared to Valkey.
