Speedtest測試網絡上傳/下載速度還是挺不錯的，windows下非常方便。Linux下也可以很方便的使用命令行speedtest來測試。speedtest是一個用Python編寫的輕量級Linux命令行工具，在Python2.4至3.4版本下均可運行。它基於Speedtest.net的基礎架構來測量網絡的上/下行速率。安裝speedtest很簡單——只需要下載其Python腳本文件。以下步驟參考了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
執行以上幾個命令就安裝好了，然后運行的時候只要輸入speedtest

同時也通過wget的方式來測試下載的速度
