Question

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这种情况，所以我进入了探查器时间轴，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。见图：

这是我的Object包。黄色是我自己的班级与我的树枝。我不明白这是什么延迟，这个大数据是什么....有人可以向我解释发生了什么以及如何优化这一点，因为在生产中如果现在它太慢了......总计时间3962毫秒

这是控制器 - 控制台没有任何奇特的效果，只有很小的改动：

class MyView (APIView):
    renderer_classes = (r.SpecialCharSeparator, ) + ...

我首先检查所有前端资源是否正确加载（脚本，图像，CSS）。这可能会大大减慢您的应用程序。您可以在firebug或开发者控制台中查看它。

Symfony加载太慢
