Question

我正在使用Code igniter框架工作，我发现页面的加载时间过长。其他页面是正常速度，当我使用探查器进行慢速页面时，我发现了以下结果：

控制器中使用上述函数来获取所有这些信息。在通过函数时，页面面临加载问题。

如何提高此页面的加载速度？

Answer 1

启用缓存服务。

$config['cache_query_string'] = FALSE;

$config['cache_path'] = 'set-a-path';

这是参考。 https://www.codeigniter.com/user_guide/libraries/caching.html

代码点火器网页的加载时间非常长
