Program

• Benchmark thread number: 8

• Program cpu cgroup: 8 core

• Comparison standard: QPS on single-core (multi-core QPS / core number), single-core performance reflects cost advantage better.

Data

• Key-value spec: key-size=32B、value-size=1KB

• Comparison dimensions: Total data size(25/50/100GB) * IO ratio(100% random write, 100% random read, 50% random write + 50% random read, 30% random write + 70% random read)
