我有一個MVC的網站，我們正在使用MVCSiteMapProvider 4.4.3與Autofac。我們使用XML和屬性的混合構建我們的網站。我們有幾百個動態節點，並且我們已啓用安全修整。過去一年，網站已經增加了大約120個控制器。所有控制器都使用根據角色而不同的授權屬性進行保護。MVC站點地圖提供程序 - SiteMapPath性能非常慢？
在我們的佈局中，我們調用@Html.MvcSiteMap().SiteMapPath()，這會在頁面加載時間內增加大約950ms。如果我們刪除該行，我們的頁面幾乎立即加載。
我們用來進行第二次加載菜單 - 但是我們把它放在一個和的RenderAction簡單緩存這在很大程度上修復了問題的結果。
這是常見的表現？是否有增強的SiteMapPath或事物表現任何明顯的方式，可能會導致性能是如此之差
如果我們刷新頁面需要第二次，只要第一
只是瀏覽約十頁剖析但CPU個循環的約70％似乎已經到：
MvcSiteMapProvider.Caching.RequestCache.GetValue(String)
MvcSiteMapProvider.RequestCacheableSiteMapNode.GetCacheKey(String)
MvcSiteMapProvider.Collections.Specialized.RouteValueDictionary.GetCacheKey()
MvcSiteMapProvider.RequestCacheableSiteMap.GetCacheKey(String)
MvcSiteMapProvider.Web.Mvc.MvcContextFactory.CreateHttpContext(ISiteMapNode)
MvcSiteMapProvider.RequestCacheableSiteMapNode.get_AreRouteParametersPreserved()
MvcSiteMapProvider.SiteMap.GetChildNodes(ISiteMapNode)
MvcSiteMapProvider.SiteMap.FindSiteMapNodeFromControllerAction(ISiteMapNode, IDictionary[StringObject], RoutMvcSiteMapProvider.Collections.CacheableDictionary`2.ContainsKey(TKey)
eBase)
MvcSiteMapProvider.RequestCacheableSiteMap.IsAccessibleToUser(ISiteMapNode)
MvcSiteMapProvider.Collections.CacheableDictionary`2.get_ReadOperationDictionary()
總來電來MVCSiteMapProvder命名空間分別爲4.34億VS 100萬所有我們自己的代碼的命名空間。
我們Autofac模塊：

其餘節點正在使用屬性添加控制器操作

你們中的大多數已經張貼是專門通過請求高速緩存以提高性能的方法。你可以發佈你的節點配置（包括動態節點提供者）和你的Autofac模塊嗎？另外，如果禁用安全修整，性能如何比較？ – NightOwl888
已更新。看起來似乎有很多行代碼被執行。更新配置等。禁用安全修整沒有任何重大差異。 – GraemeMiller
事實上，你接到這麼多的電話是非常不尋常的，我懷疑它與你的配置中的某些東西有關。您可以將您的設置與MvcMusicStore demo @ GitHub進行比較，該演示演示瞭如何與數百個動態節點和Autofac（Autofac的編譯符號集）一起工作。但最好的選擇是構建一個小型的演示項目，重現行爲，使其可以下載，並開啓一個新的問題@ GitHub。你甚至可以在構建演示時解決它。 – NightOwl888
