测试两台服务器之间的网络带宽

# 一、为什么选择了iperf #

之前做了一个项目，说要测试两台[服务器][Link 1]之间的带宽，本想通过拷贝来进行测试，后来客户觉得得出的数据没有说服性，于是改拿工具来进行测试。我们这回用的工具名字叫iperf。

iperf它是一款网络性能测试的工具，分为多个版本：Linux版、UNIX版、[Windows][]版。相比之下，Windows版更新的比较慢，而UNIX和Linux版本更新起来更快，现在最新版本是2.05，而他安装简单、方便，而且测试的出的结果很靠谱。

# 二、iperf的安装 #

iperf安装起来十分简单，只需要执行几条命令即可，因为下载的是源码，所以我们需要编译一下。

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div> 
     <div>
       1 
     </div> 
     <div>
       2 
     </div> 
     <div>
       3 
     </div> 
    </div></td> 
   <td> 
    <div> 
     <div> 
      <span>.</span> 
      <span>/</span> 
      <span>configure</span> 
     </div> 
     <div> 
      <span>make</span> 
     </div> 
     <div> 
      <span>make </span> 
      <span>install</span> 
     </div> 
    </div></td> 
  </tr> 
 </tbody> 
</table>

安装完毕之后，我们应该就能直接使用iperf这个软件了。如果没法正常使用，请到其安装目录下尝试。

其安装路应该为”/usr/local/bin/”目录下。

# 三、进行测试 #

环境介绍：

两台服务器，IP地址分别为192.168.0.1和192.168.0.2

在192.168.0.1上执行如下命令：

<table> 
 <tbody> 
  <tr> 
   <td> 
    <div> 
     <div>
       1 
     </div> 
     <div>
       2 
     </div> 
     <div>
       3 
     </div> 
     <div>
       4 
     </div> 
     <div>
       5 
     </div> 
    </div></td> 
   <td> 
    <div> 
     <div> 
      <span># iperf -s</span> 
     </div>

      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
      <span>--</span> 
     </div> 
    </div></td> 
  </tr> 
 </tbody> 
</table>

这条命令的意思是，在192.168.0.1的这台服务器上，开启服务模式。

然后在192.168.0.2这台机器上执行如下命令：

<table> 
 <tbody> 
  <tr>

[以此类推][Link 2]，我们也可以测试出从192.168.0.1这台服务器到192.168.0.2这台服务器的网络带宽。

由此，我们可以推断出，两台服务器之间为百兆带宽。
