asp.net - ASP.NET MVC 3 中的严重延迟

Question

在一页上，我看到某些 AJAX 请求有 500 毫秒的延迟，我无法解释。相关页面在加载时向同一操作触发两个 AJAX 请求，其中一个请求将被阻止。这是为什么？

ASP.NET 堆栈在 Application_AcquireRequestState 之前做什么？方法被调用？我使用了 MiniProfiler 的 ghetto 分析方法，当 Application_AcquireRequestState我可以看到对这两个 Application_PostMapRequestHandler 的调用之间花费了很长时间和Application_AcquireRequestState .

我已完全禁用 session 状态。

也许不相关，但是我遇到了同样的问题，因为我在 Global.asax Application_Start() 方法中进行了很多初始化。一旦我最小化它们，我的第一次冷加载就变得比以前快得多。
