    原来用 wireguard 回家，使用 rdp 远程桌面流畅丝滑，上个月就出现卡顿，内网应用也是一样，大家帮看看什么原因，困扰多日，万分感谢！！！

    家庭宽带联通公网 IP ，用 iperf3 测试 tcp 连接

    测试速度符合家庭宽带上传的速度，无论使用 wireguard 还是 openvpn ，用联通手机做热点或者联通宽带回家，远程桌面卡成 ppt ，不可用，用移动手机做热点回家，远程桌面有卡顿，但是可以接收。

    疑问：

    使用 wireguard 建立连接

    1. 联通是否限速了，如果限速，wireguard 建立之后的 iperf3 的测试也正常。
    2. 为什么移动热点回家，网速正常，联通网络回家，非常卡。联通对自己内部网络进行限速吗？
    3. rdp 卡是因为 wireguard 丢包严重吗？如何解决，使用 udp2raw ，还是什么方案。

    iperf 测的是吞吐量吧，测测路由，丢包，延迟抖动什么的，rdp 又不是远程串流（看电影），所以吞吐量有关系，但带宽足够之后，影响就不大了。
