编写Go程序对Nginx服务器进行性能测试的方法

        if err != nil {
            log.Fatal(err)
        }
        fcgi.Serve(unix, server)
    }()
 
    <-sigchan
 
    if err := os.Remove(SOCK); err != nil {
        log.Fatal(err)
    }
}

检查HTTP header

为公平起见，所有的请求必需大小相同。

HTTP/1.1 200 OK

启动引擎

    使用sysctl配置内核     配置Nginx     配置Nginx vhosts     用www-data启动服务     运行基准测试
