## run_bench.hash.sh 使用指南
|
||
|
||
- 脚本：`test-redis/run_bench.hash.sh`
|
||
- 默认策略：`persist_no` / `persist_everysec` / `nopersist`
|
||
- 测试模式：`set` + `prefill+get`
|
||
- 默认参数：`REQ=1000000 KEYSPACE=1000000 PIPE=128 VSIZE=32 ROUNDS=5 RETRIES=3`
|
||
|
||
### 运行示例
|
||
|
||
```bash
|
||
# 默认运行（5轮）
|
||
./test-redis/run_bench.hash.sh
|
||
|
||
# 指定大 key 参数（示例）
|
||
ROUNDS=5 REQ=1000000 KEYSPACE=1000000 PIPE=128 VSIZE=256 RETRIES=3 ./test-redis/run_bench.hash.sh
|
||
```
|
||
|

## 大Key持久化协议复测（覆盖版）
|
||
|
||
- 时间口径：2026-03-07（本次重测）
|
||
- 参数：`requests=1000000 pipeline=128 keyspace=1000000 value-size=256`
|
||
- 轮次：每种策略 `5` 轮

||
## 简要结论
|
||
|
||
1. 本次大 key（256）下，持久化开销主要体现在 `set`，`get` 相对更稳。
|
||
2. `aof_no/aof_everysec` 在 Redis 写路径的开销明显；kvstore 三策略在写路径也存在可见差异。
|
||
3. 本报告已剔除每场景 1 个异常轮次，避免单点抖动主导结论。
