                            #在屏幕上打印显示出当前的配置,配置是包括在他的配置文件$HOME/.siegerc中,

  -v, --verbose             VERBOSE, prints notification to screen.

  -c, --concurrent=NUM      CONCURRENT users, default is 10
                            #模拟有n个用户在同时访问,n不要设得太大,因为越大,siege 消耗本地机器的资源越多
  -i, --internet            INTERNET user simulation, hits URLs randomly.
                            #随机访问urls.txt中的url列表项,以此模拟真实的访问情况(随机性)

  -t, --time=NUMm           TIMED testing where "m" is modifier S, M, or H

  -r, --reps=NUM            REPS, number of times to run the test.
                            #重复运行测试n次,不能与 -t同时存在
  -f, --file=FILE           FILE, select a specific URLS FILE.
                            #指定用urls文件,默认为siege安装目录下的etc/urls.txt
