如果它可以识别正确的节点，那么它会将请求转发给该节点，等待来自该节点的响应，然后将数据返回给客户端。
If it can identify the correct node, it forwards the request to that node, waits for a response from the node, and returns the data to the client.
数据完整性在这样的情况下仍然得到维护，但相关的等待时间可能会严重影响流量和响应时间。
Data integrity is still maintained in such situations, but the associated wait times can severely impact throughput and response times.
在Ajax出现之前，对于所有数据请求，用户都要等待服务器响应。
Before Ajax, all data requests implied standing by, waiting for the server to answer.
如果采用大量短步骤，那么计算机的响应性更好，但是也意味着要等待更长时间才能得到所有数据。
A large number of short steps might mean a more responsive machine, but it also means a longer wait until getting all the data.
这是因为大多数套接字操作都是异步地进行的，其中套接字进行轮询以检查数据是否出现，而不是使得应用程序处于阻塞(等待)状态以等待响应。
This is because most socket operations are made asynchronously in that the socket is polled to see if data is present rather than having the application block (wait) for the response.
可以看到系统A向系统b发送了一个小数据包，然后等待响应包，已决定同意或拒绝登录请求。
Observe that system a sends a small data packet to system b, and waits for a response packet before granting or denying the login request.
当用户需要以特定格式来展现数据时，获取原始数据随即进行处理会延长响应时间，以至于用户放弃等待结果。

利用有效的缓存机制，可以避免到数据库的网络往返时间，绕过占用很多资源的计算，并节省服务器资源，同时改善响应时间和等待时间。
Effective cache mechanism can avoid round trip time to database, avoid calculations which occupying much time, save server resource, as well as improving the response time and waiting time.
通过上行信道，客户机可以直接向服务器发出请求，然后等待服务器的响应以获得自己所需要的数据。
The client may send a request to the server via a upstream channel, and then wait for the response for the request.
