安装

被测环境选择是某云的Ubuntu云主机，版本信息如下：

Ubuntu 18.04.1 LTS

➜ RemoteWorking

确认安装结果：

➜ RemoteWorking netperf -V
Netperf version 2.6.0

开始测试

因为我们当前只有一台测试机，所以我们就在同一台机器上启动服务端和客户端进行测试演示。

启动服务端：

➜ RemoteWorking netserver
Starting netserver with host 'IN(6)ADDR_ANY' port '12865' and family AF_UNSPEC

启动客户端开始测试：

➜ RemoteWorking netperf -H localhost
MIGRATED TCP STREAM TEST from ::0 (::) port 0 AF_INET6 to localhost (::1) port 0 AF_INET6 : demo
Recv   Send    Send

结果分析：

从上面的结果中我们可以看到：测试机的端口0的吞吐量为37435.93b/s。

转换成Mb结果为：4679.49Mb/s，约为4.57Gb/s。

Use hexadecimal.-Z passphrase Set and pass to netserver a passphraseFor those options taking two parms, at least one must be specified;
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.

常用参数：

-H host：指定远端运行netserver的server IP地址

-l testlen：指定测试的时间长度(秒)

-t testname：指定进行的测试类型(包括TCP_STREAM，UDP_STREAM，TCP_RR，TCP_CRR，UDP_RR)

-s size：设置本地系统的socket发送与接收缓冲大小

-S size：设置远端系统的socket发送与接收缓冲大小

-m size：设置本地系统发送测试分组的大小，测试PPS时值为1。测试BPS时为1400。

-M size：设置远端系统接收测试分组的大小

-p port：设置测试连接Server端的端口

-D：对本地与远端系统的socket设置TCP_NODELAY选项

-r req,resp：设置request和reponse分组的大小

常用的组合命令：
