+# benchmark使用说明
+
+此目录所有shell脚本是为了测试PaddleClas中不同模型的速度指标，如单卡训练速度指标、多卡训练速度指标等。
+
+## 相关脚本说明
+
+一共有3个脚本：
+
+- `prepare_data.sh`: 下载相应的测试数据，并配置好数据路径
+- `run_benchmark.sh`: 执行单独一个训练测试的脚本，具体调用方式，可查看脚本注释
+- `run_all.sh`: 执行所有训练测试的入口脚本
+
+## 使用说明
+
+******为了跟PaddleClas中其他的模块的执行目录保持一致，此模块的执行目录为`PaddleClas`的根目录。
+
+### 1.准备数据
+
+```shell
+bash benchmark/prepare_data.sh
+```
+
+### 2.执行所有模型的测试
+
+```shell
+bash benchmark/run_all.sh
+```
