django - Django Apache 和 Elastic Beanstalk 的 API 响应时间很慢

Question

我在 django 中有一个 POST API，并且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。

我的架构设置在 AWS Elastic Beanstalk 上。

1. 负载均衡器（使用 SSL）用作 Web 界面

2. 一个 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缩短到 500 毫秒以下

这是我用于 http.d 的 wsgi.conf
