Question

在一个页面上，我看到一些AJAX请求有500毫秒的延迟，我无法解释。有问题的页面会在加载时向同一个操作发出两个AJAX请求，其中一个将被阻止。那是为什么？

在调用Application_AcquireRequestState方法之前，ASP.NET堆栈有什么作用？我使用了MiniProfiler的贫民窟分析方法，当调用Application_AcquireRequestState时，我可以看到在对这两个Application_PostMapRequestHandler和Application_AcquireRequestState的调用之间花费了很长时间。

我完全禁用了会话状态。

也许无关，因为我在Global.asax Application_Start（）方法中做了很多初始化，所以我遇到了同样的问题。一旦我最小化它们，我的第一次冷负荷变得比以前快得多。
