在長期使用dubbo的團隊中推行springcloud確實是個難題，巨大理由之一就是rpc呼叫效率遠遠高於http，故此做一個相關效能測試，所用到的dubbo與spring系均採用官方最新版（dubbo 2.5.7 、springboot 1.5.9 、springcloud edgware）。

springcloud測試程式碼地址 https://github.com/liuchengts/spring-cloud-ts.git

dubbo測試程式碼地址 https://github.com/liuchengts/dubbo-ts.git

測試思路：使用ab工具執行10000個請求併發量為100，多次測試，取最高與最低值計算平均值
測試物件：

       1、dubbo請求：http://192.168.10.138:8082/

   2、cloud直接請求：http://192.168.10.138:3002/

   3、cloudzuul路由請求：http://192.168.10.138:3000/test-comsumer/
測試過程：
  dubbo：

發現一個現象：
dubbo的每次測試除去網路波動之外，都表現非常穩定
而cloud在第一次最慢，之後越來越快，連續測試4次以上單次測試效能超過dubbo
cloud-zuul在第一次最慢，之後也表現越來越快，連續4次以上測試 單次效能與dubbo相近，相差在0.02ms內
