Kcptun is a simple UDP Tunnel based on KCP which can speed up Shadowsocks significantly.

  1. Download Kcptun Server from Github
  2. Edit configuration file ~/kcptun/config.json
    listen is your kcp server listen address.

    For sndwnd and rcvwnd, the author recommend a value of 2048 with 100M broadband.

  3. Run Kcptun service

Client (macOS)

  1. Download Kcptun Client
  2. Edit configuration file ~/kcptun/config.json
    If you are using other broadband bandwidth, set sndwnd and rcvwnd equal to 2048*your_boardband/100Mbps.
  3. Run client service
  4. Create a new Shadowsocks Serverserver address: 127.0.0.1
    server_port: kcptun client_port
    password: same as your ss-server
    mathod: same as your ss-server

  1. Can you give some explanation on some of the settings you chose and why they are good for shadowsocks?

    “datashard”: 70,
    “parityshard”: 30,

    why are these better than the defaults?
