測試總結

數據彙總

請求鏈接數	併發數	請求失敗數	每秒處理請求數	一次併發數請求響應時間（ms）	全體請求完成時間（s）	請求成功率
10000	1000	0	11437	87.43	0.874	100.00%
50000	2000	1	18593	107.57	2.689	99.998%
10000	3000	2	19744	151.94	5.065	99.998%

 

數據分析

經過測試結果可得以下分析：

一、Nginx的每秒請求處理能力是10000+，知足需求標準；

二、隨着併發數的增大，一次併發請求的響應時間相應增大，知足需求標準；

三、隨着請求鏈接數的增長，相應的整體請求完成時間也增長，當請求鏈接數從50k增長至100k時，整體請求時間增長至2倍，具備必定的穩定性和速度性，知足需求標準；

四、當請求鏈接數和併發數依次遞增時，出現偶爾的請求失敗數，所有請求成功率大於99.99%，知足需求標準；

五、單臺服務器支持3000併發正常，知足需求標準。
