根据使用传输协议的不同，批量数据传输又分为TCP批量传输和UDP批量传输。

服务端

服务端启动服务执行

eddy@eddy:~$ netserver
Unable to start netserver with  'IN(6)ADDR_ANY' port '12865' and family AF_UNSPEC

默认情况下 netserver 开启端口号为 12865，可以通过以下命令指定服务端口（如果服务端指定端口，则客户端也需要指定服务器端口）

eddy@eddy:~$ sudo netserver -D -p 4659

specifying one value without a comma will set both parms to that
value, specifying a value with a leading comma will set just the second
parm, a value with a trailing comma will set just the first. To set
each parm to unique values, specify both and separate them with a
comma.* For these options taking two parms, specifying one value with no comma
will only set the first parms and will leave the second at the default
value. To set the second value it must be preceded with a comma or be a
comma-separated pair. This is to retain previous netperf behaviour.

Netperf缺省情况下进行TCP批量传输，即-t TCP_STREAM，用来测试进行TCP批量传输时的网络性能。

测试过程中，netperf向netserver发送批量的TCP数据分组，以确定数据传输过程中的吞吐量。

UDP_STREAM用来测试进行UDP批量传输时的网络性能。

测试UDP的网络性能时，测试分组的大小不得大于socket的发送与接收缓冲大小，否则netperf会报出错提示。

TCP_RR 方式的测试对象是多次 TCP request 和 response 的交易过程，但是它们发生在同一个 TCP 连接中，这种模式常常出现在数据库应用中。数据库的 client 程序与 server 程序建立一个 TCP 连接以后，就在这个连接中传送数据库的多次交易过程。
