+## IMDB评论情绪预测服务
+
+(简体中文|[English](./README.md))
+
+### 获取模型文件和样例数据
+
+```
+sh get_data.sh
+```
+脚本会下载和解压出cnn、lstm和bow三种模型的配置文文件以及test_data和train_data。
+
+### 启动RPC预测服务
+
+```
+python -m paddle_serving_server.serve --model imdb_cnn_model/ --port 9292
+```
+### 执行预测
+```
+head test_data/part-0 | python test_client.py imdb_cnn_client_conf/serving_client_conf.prototxt imdb.vocab
+```
+预测test_data/part-0的前十个样例。
+
+### 启动HTTP预测服务
+```
+python text_classify_service.py imdb_cnn_model/ workdir/ 9292 imdb.vocab
+```
+### 执行预测
+
+```
+curl -H "Content-Type:application/json" -X POST -d '{"words": "i am very sad | 0", "fetch":["prediction"]}' http://127.0.0.1:9292/imdb/prediction
+```
+
+### Benchmark
+
+设备 ：Intel(R) Xeon(R)  Gold 6271 CPU @ 2.60GHz * 48
+
+模型 ：[CNN](https://github.com/PaddlePaddle/Serving/blob/develop/python/examples/imdb/nets.py)
+
+server thread num ： 16
+
+测试中，client共发送25000条测试样本，图中数据为单个线程的耗时，时间单位为秒。可以看出，client端多线程的预测速度相比单线程有明显提升，在16线程时预测速度是单线程的8.7倍。
