初始數值
在開始系統架構之前，我們需要先了解到在一般正常情況下，伺服器與資料庫毫無任何處理，接收到請求就固定回傳一個空白頁面的情況下，分別測試 10 個連線 300 次連續點擊、100 個連線 600 次連續點擊、300 個連線 1500 次連續點擊，各自會得到的數值。
首先以測試 10 個連線 300 次連續點擊開始。

接著測試100 個連線 600 次連續點擊，我們可以明顯地看到連線時間(Connection Times)的部分急遽上升。

最後測試 300 個連線 1500 次連續點擊，可以明顯地看到連線時間(Connection Times)的部分急遽上升以外，觀察到平均每秒可回應要求(Requests per second)大約著落於每秒可以處理大約接近 5 個回應。
