使用 Redis 快取

由於我們將系統架構改為隊列(Queue)的方式，Laravel 的隊列(Queue)功能允許你將一個耗時的任務(Job)延遲處理，例如像寄送 e-mail，這會使得你的應用程式對網頁請求有更快的反應，隊列(Queue)知道這個任務(Job)應該是被放到隊列(Queue)裡，而不是直接執行，所以我們嘗試將隊列放入 Redis 快取當中做測試。
首先從 10 個連線 300 次連續點擊開始。

再來測試 100 個連線 600 次連續點擊，我們可以發現到與原本的「v2」版本其實沒有差很多。

最後測試 300 個連線 1500 次連續點擊，與原本的「v2」版本其實沒有差很多，可能在隊列的改善版本已經解決了大多數的問題，畢竟隊列(Queue)功能允許你將一個耗時的任務(Job)延遲處理，也就是將最主要的寫入問題給延遲處理了，那麼回應(Response)的部分就會與初始無異。

最後我們測試查詢訂單的部分，測試 300 個連線 1500 次連續點擊，由於我們已經把快取改由 Redis 做處理，平均每秒可回應要求(Requests per second)也著落於接近每秒 5 個回應。
