我已将应用程序从Symfony 2.1升级到Symfony 3.4。当我在localhost中测试新应用程序时，它可以完美，快速地运行，甚至更快 比以前的应用程序。但是，当我在服务器上推送应用程序时，对于 新应用程序，而Symfony 2.1下的应用程序将在1秒内加载到他的服务器上。
两个版本中的数据库参数是相同的，我已经努力了很多天以找出问题所在。特别是 我不知道这是应用程序还是服务器出现问题。
为了更加精确，以下是这两个应用程序的详细信息：

您知道为什么新应用程序中会有这样的加载时间吗？
谢谢。
编辑：
您好，@ habibun，谢谢您的回答。
下面是探查器中的性能图片：
问题似乎是由于需要105秒的“控制器”行所致。有没有办法减少这条线的加载时间？
此外，您能告诉我如何在Symfony 3.4上浏览config.php吗？我应该使用哪个命令？抱歉，如果我问一个愚蠢的问题，我是Symfony的新手。
