我有一些來自 online.net 的專用伺服器，它們都很棒。但最近我發現我的新伺服器上的連線有問題。它是 Dedibox MD SSD 2015 Gen2 (Ubuntu 16.04)。
我發現令人困惑的問題是來自 speedtest.net 的速度測試，如下所示：
Testing download speed................................................................................
Download: 107.05 Mbit/s
Testing upload speed....................................................................................................
Upload: 3.94 Mbit/s
上傳到 S3 等裝置的速度約為 80MB/s
線上 ping 測試如下：
iperf -c ping.online.net
------------------------------------------------------------
Client connecting to ping.online.net, TCP port 5001
TCP window size: 85.0 KByte (default)
------------------------------------------------------------
[ 3] local xx.xx.xx.xx port 48026 connected with xx.xx.xx.xx port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 1.10 GBytes 942 Mbits/sec
thinkbroadband 的測試文件如下所示：
wget http://ipv4.download.thinkbroadband.com/1GB.zip

正如您所看到的，這些結果很奇怪嗎？主要是speedtest.net的結果。
任何有關可能導致此問題的原因的幫助將不勝感激。
