+`qt-unified-windows-x86-4.0.1-1-online.exe` 預設的 server 真的很慢，甚至會發生校驗錯誤的情況。
+可以在[Qt Downloads](https://download.qt.io/static/mirrorlist/)選 mirror server，然後在安裝的時候指定使用它。
+
+例如我選的是 Yamagata University 的mirror server，如下：
+```cmd
+qt-unified-windows-x64-4.7.0-online.exe --mirror https://ftp.yz.yamagata-u.ac.jp/pub/qtproject/
+```
+
+下載速度從1 ~ 2 MB/s 進步到 25MB/s 左右。
