Question

我有一个项目，已经在EC2实例上正常运行了一年以上。从后端到前端的响应通常在600毫秒内。在此服务器上，我们将其称为服务器A，前端和后端托管在同一台服务器上，数据库托管在MongoDB Atlas上。

现在我们使用的是docker，前端和后端位于单独的容器中，每个容器托管在不同的实例上。现在，响应时间已跃升至3.36s。因此从600 毫秒到3.36 秒。我正在使用与服务器A相同的数据库服务器。

我真的很想听听您关于如何优化PHP，Laravel和Nginx，以在Docker上获得最快响应时间的想法。

这是我的配置文件DockerFile，start.sh和nginx.conf

在我的情况下（mac os），我发现卷挂接正在受到打击。

通过应用此应用，性能提高了50％。

 volumes: 
  - .:/var/www/html:cache

您可以使用其他音量标志来提高性能

一致：完美的一致性（主机和容器在任何时候都具有相同的安装视图）
已缓存：主机的视图具有权威性（允许在主机上的更新出现在容器中之前延迟）
已授权：容器的视图具有权威性（允许在容器上的更新出现在主机上之前的延迟）

注意：仅适用于Docker版本Docker 17.04 CE Edge

PHP7 + Laravel + Nginx在Docker上非常慢
