ApacheBench(ab) 用來測試 apache 執行效率.

ab 使用

ab使用範例:
要執行 1000 次的 connection, 20 次的 concurrent (並行, 同時):

語法: ab -n 1000 -c 20 http://localhost/abc.php

產生出來的結果. 要注意的是以下幾個:

  • Time taken for tests: 總共執行花了多久的時間.(以上 1000 次共多久)
  • Requests per second: 每秒平均可以處理多少個 connection.

    請不要拿來測試別人的網站,不然會被認為是駭客或把你的IP擋住
    個人小意見
