用speedtest进行对linux系统的网络测试。首先下载speedtest的脚本并配置：
$ wget https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py $ chmod a+rx ./speedtest.py $ sudo mv speedtest.py /usr/local/bin/speedtest $ sudo chown root:root /usr/local/bin/speedtest然后进行网络测试只需要输入speedtest即可：
-sh-4.2$ speedtest Retrieving speedtest.net configuration... Testing from China Telecom (202.103.201.77)... Retrieving speedtest.net server list... Selecting best server based on ping... Hosted by NanningTelecom (Nanning) [0.00 km]: 12.67 ms Testing download speed............................................ Download: 5.40 Mbit/s Testing upload speed............................................. Upload: 1.56 Mbit/s -sh-4.2$
以下是另一台服务器：
[tingguang@localhost initial_assembly]$ speedtest Retrieving speedtest.net configuration... Testing from China Telecom (202.103.201.73)... Retrieving speedtest.net server list... Selecting best server based on ping... Hosted by NanningTelecom (Nanning) [0.00 km]: 8.347 ms Testing download speed........................................ Download: 93.23 Mbit/s Testing upload speed.........................................Upload: 19.00 Mbit/s[tingguang@localhost initial_assembly]$速度相差太大了
