标签： javascript google-chrome time server loading

最近我的网站遇到了问题：它开始加载真的很慢，我不知道为什么会这样。我用分析器查看了它，发现我的URL的结尾 - 这是一个作为查询字符串传递的ID - 大约需要13秒才能加载。我不知道造成这种情况的原因。我检查了脚本，部分禁用它们并且一起禁用但似乎没有任何帮助。例如： www.mysite.com/flat/5 /

我有时会看到，如果Chrome无法找到像图片这样的内容，则需要很长时间才能加载，但我没有丢失Chrome要加载的文件。

我附上截图，向您展示探查器显示的内容： enter image description here

编辑：添加了服务器端代码

看起来这是从服务器加载的页面花了这么长时间。无论是什么在另一端查找ID似乎都很慢。我会看一下整体服务器的速度，但也要确保你的数据库上有索引，这样可以加快速度。
