Php Symfony加载太慢

我正在构建一个Symfony应用程序，当我处理它时，它太慢了。我想知道是什么导致了这一点，所以我进入了探查器时间线，看看发生了什么，但我很惊讶所有这些类都有非常大的数据10 MB、22 MB等等。如图所示：

这是我的对象包。黄色是我自己的班级和我的树枝。我不明白什么是延迟，什么是大数据。。。。有人能告诉我发生了什么，以及如何优化这一点，因为在生产中，如果它像现在这样，它太慢了。。。总时间3962毫秒

这是控制器-只需稍作更改即可从控制台生成：

我首先要检查您的所有前端资源是否正确加载（脚本、图像、css）。 这会大大降低应用程序的运行速度。

您可以在firebug或开发人员控制台中进行检查。

你好，乔治，介意展示一下您的模板吗？请记住，在开发环境中，有些事情会减慢应用程序的速度：较小的缓存、评测、调试、日志记录等。这并不一定意味着，您的prod环境也会变慢。好吧，但太慢了，我无法想象这需要4秒。。。我已经包含代码：）缓存后的第一个请求：clear将始终比以下请求慢。是这样吗？不，不是这样。如何切换到生产模式？对于生产模式，您只需使用常规URL，而无需通过/app_dev.phphphello-George访问，介意显示您的模板吗？请记住，在开发环境中，有些事情会减慢应用程序的速度：较小的缓存、评测、调试、日志记录等。这并不一定意味着，您的prod环境也会变慢。好吧，但太慢了，我无法想象这需要4秒。。。我已经包含代码：）缓存后的第一个请求：clear将始终比以下请求慢。是这样吗？不，不是这样。如何切换到生产模式？对于生产模式，您只需使用常规URL，而无需通过/app_dev.phpI访问。我显示，在加载symfony探查器控制台时间线中的任何脚本之前，我在php中只有4秒的延迟。查看前端，就像js脚本一样，查看db查询，您从数据库中获取了多少结果？对于许多查询（如图所示），您是否配置了php？（PHP7，启用opcache？）我已经优化了许多站点，但不是基于symfony的。事实是，这是管理，存在许多javascript依赖项。但是我看到脚本每天加载50毫秒，明天将进行更多的调查。关于opcache，你是对的，我忘了。。。。这将是早上的第一件事！在加载symfony分析器控制台时间线中的任何脚本之前，我在php中只有4秒的延迟。看看前端，就像js脚本一样，看看db查询，你从db中获取了多少结果？对于许多查询（如图所示），您是否配置了php？（PHP7，启用opcache？）我已经优化了许多站点，但不是基于symfony的。事实是，这是管理，存在许多javascript依赖项。但是我看到脚本每天加载50毫秒，明天将进行更多的调查。关于opcache，你是对的，我忘了。。。。这将是早上的第一件事！
