[AB] ApacheBench – 網站壓力測試工具

Intro

ApacheBench壓力測試工具，Windows安裝XAMPP即Apache就有內建。

執行檔案

以Windows XAMPP為例，找到安裝目錄下Apache執行檔目錄：

D:\xampp\apache\bin\ab.exe

HTTPS傳輸

Windows XAMPP使用ab.exe測試HTTPS的網站會有錯誤：

SSL not compiled in; no https support

HTTPS協定是使用abs.exe執行：

D:\xampp\apache\bin\abs.exe

Linux的apache2-utils即等於abs.exe

使用方法

同時 10 個連線，連續訪問 100 次 (每個 Request 執行完後自動重連)

ab -n 100 -c 10 http://www.example.com/

同時 10 個連線，連續訪問 100 次，並且使用 Keep-Alive 方式連線 (Web Server需支援Keep-Alive功能)

ab -n 100 -c 10 -k https://www.example.com/
