Speedtest测试网络上传/下载速度还是挺不错的，windows下非常方便。Linux下也可以很方便的使用命令行speedtest来测试。speedtest是一个用Python编写的轻量级Linux命令行工具，在Python2.4至3.4版本下均可运行。它基于Speedtest.net的基础架构来测量网络的上/下行速率。安装speedtest很简单——只需要下载其Python脚本文件。以下步骤参考了linuxtoday的文章。

wget https://raw.github.com/sivel/speedtest-cli/master/speedtest.py
chmod a+rx speedtest.py
mv speedtest.py /usr/local/bin/speedtest
chown root:root /usr/local/bin/speedtest

执行以上几个命令就安装好了，然后运行的时候只要输入
speedtest

如果你想分享测试结果，你可以使用参数“–-share”。它将会把你的测试结果上传到Speedtest.net服务器并以图形的方式分享给其他人。

如果你对目前所有可用的Speedtest.net服务器感兴趣，你可以使用参数“–list”。它会打印出所有的Speedtest.net服务器（按照离你的地理距离由近及远排序）。

在上面的列表中，每一行前面都有一个与服务器对应的ID。如果想使用指定的节点来测试你的网速，你只需要在speedtest命令后指定其ID即可。例如，如果想使用上图中的QuadraNet服务器，你只需要指定相对应的服务器ID5726即可。
