linux环境下，如何使用speedtest测速。其实superbench一键包也是带这个网络带宽测速的,今天单独来说说speedtest测速.

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:

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

安装完毕后，在机器上面敲命令speedtest，就会出现下载上传速度。

如上图所示，我拿美国KT洛杉矶云主机测试了下速度，果然是有200M的速度。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5031服务器，你只需要指定相对应的服务器ID5031即可。

speedtest --server 5031
