我从 online.net 上购买了一些专用服务器，它们都很棒。但最近我发现我的新服务器的连接存在问题。它是 Dedibox MD SSD 2015 Gen2（Ubuntu 16.04）。
我发现令人困惑的问题是 speedtest.net 上的速度测试结果如下：
Testing download speed................................................................................
Download: 107.05 Mbit/s
Testing upload speed....................................................................................................
Upload: 3.94 Mbit/s
上传到 S3 之类的速度大约为 80MB/s
在线 ping 测试如下：
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 的测试文件也如下所示：
wget http://ipv4.download.thinkbroadband.com/1GB.zip

如您所见，这些结果很奇怪？主要是 speedtest.net 的结果。
如果能提供任何关于导致此问题的原因的帮助，我们将非常感激。
