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.
