Laravel 数据库 MySQL 查询需要很长时间

Question

我有一个连接到我的数据库的页面，但在收集所有数据后加载页面大约需要 1 分钟。

我做错了什么，或者我可以做些什么来加快这个过程？

控制器

    /**
     * Display a listing of the resource.

Answer 1

首先，这听起来很长。

查询看起来确实很详细，但应该不会超过 1 分钟。

您可以尝试使用 eloquent，但这只会比原始查询快一点。

你没有提到的是：

这是本地服务器还是远程服务器？ 如果您使用的是远程服务器，我的解决方案是在 mysqld 下的 my.ini / my.cnf 中使用 "skip-name-resolve" 并更新您的 key_buffer_size。

如果这不能提高速度，则可以查看该特定服务器的资源。
