测试环境&条件

3 台 16C 20G 内存的 docker 容器作为 server node (3 副本)
2 ~ 8 台 8C docker 容器作为 client
24 个 raft 复制组，平均每台 server node 上各自有 8 个 leader 负责读写请求，不开启 follower 读
压测目标为 JRaft 中的 RheaKV 模块，只压测 put、get 两个接口，其中 get 是保证线性一致读的，key 和 value 大小均为 16 字节
读比例 10%，写比例 90%

目前的测试场景比较简单，以后会增加更多测试场景

测试场景1

场景1: 测试条件

Client 数量	Client-Batching	Storage-Type	读写比例	Replicator-Pipeline	key 大小	value 大小
8	开启	MemoryDB	1:9	开启	16 字节	16字节

场景1: 结果汇总：

8 个 client 一共达到 40w+ ops，p95 RT 在 8ms 以内
3 个 server 节点负载没达到极限 load 15 左右，cpu 40% 左右

场景1: 3 个 server 机器负载：

场景2: 测试条件

Client 数量	Client-Batching	Storage-Type	读写比例	Replicator-Pipeline	key 大小	value 大小
8	开启	RocksDB	1:9	开启	16 字节	16字节

场景2: 结果汇总

8 个 client 一共达到 25w+ ops, p95 RT 在 20ms 以内
3 个 server 节点负载没达到极限 load 10 左右，cpu 30% 左右，还可以增加 client，client 发送能力受限

测试场景3

场景3: 测试条件

Client 数量	Client-Batching	Storage-Type	读写比例	Replicator-Pipeline	key 大小	value 大小
2	关闭	Memory	1:9	开启	16 字节	16字节

场景3: 结果汇总

2 个 client 一共达到 10w+ ops，p95 RT 在 10ms 以内
3 个 server 节点负载达到极限 load 接近 20，cpu 超过 50%
ops 降低的原因在于关闭了 client-batching 后 RPC(bolt) 层面也出现了瓶颈，所以还是建议打开 client-batching 开关，client-batching 没有副作用，完全不会影响单个消息的延迟

场景3: 3 个 server 机器负载

场景4: 测试场景4

场景4: 测试条件

Client 数量	Client-Batching	Storage-Type	读写比例	Replicator-Pipeline	key 大小	value 大小
2	关闭	Memory	1:9	关闭	16 字节	16字节

场景4: 结果汇总

2 个 client 一共达到 7.5w ops，p95 RT 在 15ms 以内
3 个 server 节点负载达到极限 load 接近 20 (有一台超过 20), cpu 超过 50%
ops 降低的原因在于关闭了 client-batching 后 RPC(bolt) 层面也出现了瓶颈，所以还是建议打开 client-batching 开关，client-batching 没有副作用，完全不会影响单个消息的延迟
