HotKV tops Redis, Valkey and Dragonfly on most commands in three-node cluster test

A benchmark compared HotKV, Redis, Valkey and Dragonfly deployed as three-node clusters on AWS servers, matching how Redis and Valkey are typically scaled across cores. HotKV posted the highest throughput on eight of nine tested commands, reaching 92.3 million GETs per second versus 57.3 million for Redis, 52.9 million for Valkey and 22.5 million for Dragonfly. Redis and Valkey led on APPEND, and some load generators were near their limits, so the reported figures are lower bounds. The authors argue that a cluster layout is fairer than the earlier single-instance tests, since Redis and Valkey run one thread per process. All tests ran with persistence disabled on 5 million keys with 256-byte values, using median results from two 15-second runs.
