+## 高kps场景

+## 分布式场景客户端延迟
+在batch查询场景下，单次batch查询耗时是业务方（特别是在线预估服务）非常关心的敏感指标。在分布式场景下，单次batch查询往往要并发请求下游所有分片server，此时batch查询耗时取决于最慢的分片请求。我们在下文给出了一个典型分布式场景下的batch查询耗时。
+
+测试条件:
+cube分片数:10 
+client机器ping下游server机器约0.06ms

+
+## 结语
+上述表格主要阐述了cube server单机性能，在生产环境下，对于更高的kps(qps)压力我们可以方便地通过增加副本的方式来增强集群负载能力。 在模型大小超过单机内存限制时，我们亦可通过部署多数据分片的分布式集群来提供服务。
+整体来说，cube性能能够满足当前业界各类预估服务的kv访问需求。
+
+## PS
+本文所列性能均为cube原始代码版本性能，如果根据实际情情况做适当调优：如链入tcmalloc or jemalloc、 进行numa绑定 以及 打开编译优化参数等等，都有可能进一步明显提升cube server的性能表现。

doc/HTTP_INTERFACE.md

+# HTTP Inferface
+
+Paddle Serving服务均可以通过HTTP接口访问，客户端只需按照Service定义的Request消息格式构造json字符串即可。客户端构造HTTP请求，将json格式数据以POST请求发给serving端，serving端**自动**按Service定义的Protobuf消息格式，将json数据转换成protobuf消息。
+
+本文档介绍以python和PHP语言访问Serving的HTTP服务接口的用法。
+
+## 1. 访问地址
+
+访问Serving节点的HTTP服务与C++服务使用同一个端口（例如8010），访问URL规则为：
+
+```
+http://127.0.0.1:8010/ServiceName/inference
+http://127.0.0.1:8010/ServiceName/debug
+```
+
+其中ServiceName应该与Serving的配置文件`conf/services.prototxt`中配置的一致，假如有如下2个service：
+
+```protobuf
+services {
+  name: "BuiltinTestEchoService"
+  workflows: "workflow3"
+}
+
+services {
+  name: "TextClassificationService"
+  workflows: "workflow6"
+}
+```
+
+则访问上述2个Serving服务的HTTP URL分别为：
+
+```
+http://127.0.0.1:8010/BuiltinTestEchoService/inference
+http://127.0.0.1:8010/BuiltinTestEchoService/debug
+
+http://127.0.0.1:8010/TextClassificationService/inference
+http://127.0.0.1:8010/TextClassificationService/debug
+```
+
+## 2. Python访问HTTP Serving
+
+Python语言访问HTTP Serving，关键在于构造json格式的请求数据，可以通过以下步骤完成：
+
+1) 按照Service定义的Request消息格式构造python object
+2) `json.dump()` / `json.dumps()` 等函数将python object转换成json格式字符串
+
+以TextClassificationService为例，关键代码如下：
+
+```python
+# Connect to server
+conn = httplib.HTTPConnection("127.0.0.1", 8010)
+
+# samples是一个list，其中每个元素是一个ids字典：
+# samples[0] = [190, 1, 70, 382, 914, 5146, 190...]
+for i in range(0, len(samples) - BATCH_SIZE, BATCH_SIZE):
+    # 构建批量预测数据
+    batch = samples[i: i + BATCH_SIZE]
+    ids = []
+    for x in batch:
+        ids.append({"ids" : x})
+    ids = {"instances": ids}
+
+    # python object转成json
+    request_json = json.dumps(ids)
+
+    # 请求HTTP服务，打印response
+    try:

+## 3. PHP访问HTTP Serving
+
+PHP语言构造json格式字符串的步骤如下：
+
+1) 按照Service定义的Request消息格式，构造PHP array
+2) `json_encode()`函数将PHP array转换成json字符串
+
+以TextCLassificationService为例，关键代码如下：
+
+```PHP
+function http_post(&$ch, $data) {
+    // array to json string
+    $data_string = json_encode($data);
+
+    // post data 封装
+    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
+
+    // set header
+    curl_setopt($ch,
+            CURLOPT_HTTPHEADER,
+            array(
+                'Content-Length: ' . strlen($data_string)
+            )
+    );
+
+    // 执行
+    $result = curl_exec($ch);
+    return $result;
+}
+
+$ch = &http_connect('http://127.0.0.1:8010/TextClassificationService/inference');
+
+$count = 0;
+
+# $samples是一个2层array，其中每个元素是一个如下array：
+# $samples[0] = array(
+#                   "ids" => array(
+#                                 [0] => int(190),
+#                                 [1] => int(1),
+#                                 [2] => int(70),
+#                                 [3] => int(382),
+#                                 [4] => int(914),
+#                                 [5] => int(5146),
+#                                 [6] => int(190)...)
+#                    )
+
+for ($i = 0; $i < count($samples) - BATCH_SIZE; $i += BATCH_SIZE) {
+    $instances = array_slice($samples, $i, BATCH_SIZE);
+    echo http_post($ch, array("instances" => $instances)) . "\n";
+}
+
+curl_close($ch);
+```
