In a comparative benchmark between Valkey 8.1 and Redis 8.2, Valkey demonstrated superior memory efficiency and stable throughput when handling 50 million sorted set operations, a critical feature for high-demand environments like Raider.IO, which tracks thousands of real-time player activities. Valkey 8.1 used 28% less memory than Redis 8.2, resulting in reduced operational costs and improved capacity planning due to its consistent performance under pressure. While Redis initially showed higher throughput, Valkey maintained a steadier pace, finishing with 570k inserts per second compared to Redis's 530k, highlighting its robustness in high-volume scenarios. The benchmark, conducted on an AWS c8g.2xl instance using Docker and Rust, underscores Valkey's advantages in environments where memory efficiency and predictability are key to maintaining responsive services during peak loads.
