使用Django Apache和Elastic Beanstalk缩短API响应时间

Question

我在django中有一个POST API，我已经为应用程序安装了New Relic APM。 django处理请求所需的时间约为250毫秒，但响应时间（从邮递员测量）约为2.5秒。

我的架构是在AWS Elastic Beanstalk上设置的。

1. 负载均衡器（使用SSL）用作Web界面

2. Linux实例通过WSGI与Django应用程序一起运行Apache

连续请求的响应时间从2.5秒到600毫秒不等。如何识别问题并将响应时间降至500毫秒以下

这是http.d

的wsgi.conf
