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
