php - Docker 项目要慢得多

问题描述

我所做的是将项目转移到使用 docker 容器。这个项目非常大，我最终得到了大约 12 个容器。

现在有 2 台相同的服务器运行 Ubuntu 18.04。

  1. 在第一台服务器上，项目照常部署：运行Nginx、PHP7.2-fpm、MySQL5.7等服务。
  2. 在第二台服务器上，在 docker 上提出了一个项目

问题的症结在于，在测试两台服务器处理多个请求的速度时，docker上的服务器表现出的性能要差得多。

这是原始服务器上的项目（使用 ApacheBench n100 c100 测试）：

我已经查看了很多手册、文章和其他内容。尝试了很多建议。没有什么帮助。

  1. 在 docker 中修改网络
  2. 在php中禁用调试器
  3. 使用了不同版本的 docker-compose
  4. 配置 docker 守护进程的规则

所有操作都为一位用户带来了足够好的速度。但是在负载下，docker 非常慢。

这是 docker-compose.yml（PHP、Mysql、Nginx 位于后面部分）：

嗯，这就是问题所在。如何解决项目负载高的速度问题？为什么docker在负载下这么慢？有任何想法吗？

如果您需要更多数据，我会附上。
