用法

gt --help
Fast WebSocket(s)/HTTP(s)/TCP relay proxy with WebRTC P2P supports.

Usage: gt [OPTIONS] [COMMAND]

Commands:
  server  Run GT Server
  client  Run GT Client
  help    Print this message or the help of the given subcommand(s)

Options:
  -c, --config <CONFIG>
          Path to the config file or the directory contains the config files

  -s, --signal <SIGNAL>
          Send signal to the running GT processes

          Possible values:
          - reload:  Send reload signal
          - restart: Send restart signal
          - stop:    Send stop signal

  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

配置文件

配置文件可以通过 Web 管理后台编辑生成,推荐直接使用 Web 管理后台编辑。

服务端

使用默认配置运行,运行后可从日志获取 Web 管理后台地址,用浏览器打开后,进行配置项编辑:

gt server

通过指定配置文件运行:

gt server -c ./config.yml

客户端

使用默认配置运行,运行后可从日志获取 Web 管理后台地址,用浏览器打开后,进行配置项编辑:

gt client

通过指定配置文件运行:

gt client -c ./config.yml

批量启动

通过指定配置文件目录批量启动:

gt -c ./conf.d

性能测试

第一组(MacOS环境+nginx测试)

通过 wrk 进行压力测试本项目与 frp 进行对比,内网服务指向在本地运行 nginx 的测试页面,测试结果如下:

Model Name: MacBook Pro
Model Identifier: MacBookPro17,1
Chip: Apple M1
Total Number of Cores: 8 (4 performance and 4 efficiency)
Memory: 16 GB
