使用方法: wrk <选项> <被测HTTP服务的URL>                            
  Options:                                            
    -c, --connections <N>  跟服务器建立并保持的TCP连接数量  
    -d, --duration    <T>  压测时间           
    -t, --threads     <N>  使用多少个线程进行压测   
                                                      
    -s, --script      <S>  指定Lua脚本路径       
    -H, --header      <H>  为每一个HTTP请求添加HTTP头      
        --latency          在压测结束后,打印延迟统计信息   
        --timeout     <T>  超时时间     
    -v, --version          打印正在使用的wrk的详细版本信息
                                                      
  <N>代表数字参数,支持国际单位 (1k, 1M, 1G)
  <T>代表时间参数,支持时间单位 (2s, 2m, 2h)
