Runner hardware/software

OS	Ubuntu 24.04.4 LTS
Kernel	6.17.0-1022-azure
CPU	AMD EPYC 9V74 80-Core Processor
Logical CPUs	4
Memory	15.6GiB
/dev/shm	11.7GiB
RocksDB block cache	7.8GiB

num=50000000 | key_size=8 | value_size=50

On-disk DB size (1.9GiB) ≤ block cache (7.8GiB) — the dataset fits in cache, so this bench is a CPU and memory comparison.

On readrandom (the fairest comparison), ToplingDB zipkeyvalue is 19% memory / 4.47x speed vs RocksDB v8.10.
In production the working set typically does not fit, so cache misses dominate. The same RAM holds more ToplingDB data, which cuts I/O and widens the gap.
ToplingDB dcompact can offload most of that CPU and memory cost.
