使用IIS配置本地站点，然后编译项目完成后，浏览器加载页面变得非常慢，之前虽然会慢一些，但加载时最多可能需要1到2分钟（可能包含一些预编译）加载dll文件），但现在变得非常慢，第一次需要6到7分钟才能加载。
我使用'Fusion Log Viewer'来查看程序集绑定日志加载，发现一些dll需要很长时间。
请注意，下图显示了页面加载程序集： assembly loding image
我参考了这个链接：
http://blog.lavablast.com/post/2010/12/01/Slash-your-ASPNET-compileload-time.aspx
然后我设置了文件“C：\ Windows \ Microsoft.NET \ Framework64 \ v4.0.30319 \ Config \ web.config” 配置节点：
<Compilation batch = "false" optimizeCompilations = "true">
但效果并不明显，而访问某些用户控件的时间仍然很慢。
这里我选择了一个相对较慢的dll加载日志，希望有人知道因为什么这么慢，帮助分析。

事实上，我一直在想为什么会出现这个问题，而且我从来没有讨论过IIS配置
