Pipelined throughput that high usually means the loadgen is the thing you're measuring. Past ~5M ops/sec we needed 3 separate memtier hosts to keep the client off the critical path. Any p99 numbers alongside it?

Yes, p99s are in the README file in the github repo. at pipeline 16, GET/SET p99 was 0.36/0.42 ms for KiviDB, 0.88/1.07 ms for Dragonfly 2.0.2 and 2.2/2.7 ms for Redis 8.10. That is one of the differentiators, the p99 is sub millisecond
