We only achieve a slow Internet speed when use single shadowsocks.Because the shadowsocks with TCP mode.Well know the TCP mode have three shake hands,but here kcptun with UDP mode.

First:Download kcptun progress and upload to server
website:"https://github.com/xtaci/kcptun/releases"
wget https://github.com/xtaci/kcptun/releases/download/v20200409/kcptun-linux-amd64-20200409.tar.gz
tar -zvxf kcptun-linux-amd64-20200409.tar.gz
Second:Write kcptun config file
{
"listen": ":*****",
"target": "127.0.0.1:*****",
"key": "123456",
"crypt": "none",
"mode": "fast3",
"mtu": 1370,
"sndwnd": 8192,
"rcvwnd": 2048,
"datashard": 10,
"parityshard": 3,
"dscp": 0,
"nocomp": true,
"quiet": false,
"pprof": false,
"tcp": true,
"sockbuf": 33554433,
"smuxver": 1,
"smuxbuf": 33554433
}
listen: mean kcptun listen port
target: mean transfer to shadowsocks port.127.0.0.1 represent local server."****" mean shadowsocks' port.
