测试总结

数据汇总

请求连接数	并发数	请求失败数	每秒处理请求数	一次并发数请求响应时间（ms）	全体请求完成时间（s）	请求成功率
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%

数据分析

通过测试结果可得如下分析：

1、Nginx的每秒请求处理能力是10000+，满足需求标准；

2、随着并发数的增大，一次并发请求的响应时间相应增大，满足需求标准；

3、随着请求连接数的增加，相应的总体请求完成时间也增加，当请求连接数从50k增加至100k时，总体请求时间增加至2倍，具有一定的稳定性和速度性，满足需求标准；

4、当请求连接数和并发数依次递增时，出现偶尔的请求失败数，全部请求成功率大于99.99%，满足需求标准；

5、单台服务器支持3000并发正常，满足需求标准。
