为何开启kcptun之后反而速度更慢了呢，未开启用fast.com测速5-8Mbps，开启后反而降到1Mbps左右

服务器端是搬瓦工VPS+SS-libev+server_linux_amd64； 客户端是SSx-NG+client_darwin_amd64

server端和client端都是这么设置的嘛？ mode用fast2还是fast3？ datashard、parityshard、dscp这些参数呢？

[miny1233]

mode fast3 datashard5 parityshard2 dscp0

[csco11298754]

mode fast3 datashard5 parityshard2 dscp0

你开了BBR加速吗?原版的还是魔改的

国内运营商对家宽UDP会限制到1M, 可以试试 --tcp 。
