測試過在MT7688上也能用，(測速時7688 CPU 接近滿載)。
首先來安裝
pip install speedtest-cli接下來你可以試用一下
speedtest
執行結果如下
boywhyde-Mac-mini:~ boywhychen$ speedtest

boywhyde-Mac-mini:~ boywhychen$ 看起來我的網速沒有灌水
如果你要用在程式中呼叫取值，可以多下一個參數將內容轉換成JSON包裝
speedtest --json執行結果如下 ，不過用JSON格式會得到原始bit/s的資料，不會將速度轉換成Mbit/s
boywhyde-Mac-mini:~ boywhychen$ speedtest --json
{"download": 5544023.1582899, "timestamp": "2017-02-11T16:26:39.586203", "ping": 15.59, "upload": 2433976.4864097824, "server": {"latency": 15.59, "name": "Kaohsiung", "url": "http://phc-sptest.elinx.com.tw/speedtest/upload.php", "country": "Taiwan", "lon": "120.2667", "cc": "TW", "host": "phc-sptest.elinx.com.tw:8080", "sponsor": "TFN Media Co., Ltd.", "url2": "http://phc-speedtest.elinx.com.tw/speedtest/upload.php", "lat": "22.6333", "id": "2189", "d": 8.274083461500231}}
boywhyde-Mac-mini:~ boywhychen$ 接下來我們還可以透過參數將選擇最近的Server ID，滅少接數Server List時間
boywhychen$ speedtest --server 2189
我們發現它少了以下動作

來看一下在Mac上Run 可以節省多少時間
(我在高雄，所以我以剛才回傳的JSON字串中的ID 做為固定的Server，若在不同
地點，建議先取得一次測試的JSON資料，拿到最好的Server ID再進行固定ID）

會節省多少時間呢 ？

在7688上測試，指定Server可以節省近5秒鐘，且測試節果和Mac測試的差不多，
雖然上傳稍微慢了一點，但如果有一個需要監控網路速度需求的話，7688小而省丫。
