使用最新版本的任务并行库(TPL)，根据. net版本。必须根据不同的用途选择正确的TPL模块。

基本的建议是遵循REST原则，以下几点将这些原则中的一些与ASP。NET MVC框架:

Make your controllers stateless - this is more of a 'Web performance / scalability' suggestion (as opposed to micro/machine level performance) and a major design decision that would affect your applications future - especially in case it becomes popular or if you need some fault tolerance for example. Do not use Sessions Do not use tempdata - which uses sessions Do not try to 'cache' everything 'prematurely'. Use Forms Authentication Keep your frequently accessed sensitive data in the authentication ticket Use cookies for frequently accessed non sensitive information Make your resources cachable on the web Utilize ETags Use expiration Write your custom ActionResult classes if necessary Utilize reverse proxies Compile your JavaScript. There is Closure compiler library to do it as well (sure there are others, just search for 'JavaScript compiler' too) Use CDNs (Content Delivery Network) - especially for your large media files and so on. Consider different types of storage for your data, for example, files, key/value stores, etc. - not only SQL Server Last but not least, test your web site for performance

以下是可能的改进来源:

一般

利用分析器来发现应用程序中的内存泄漏和性能问题。我个人建议dotTrace 在生产环境和性能分析期间，以发布模式(而不是调试模式)运行站点。释放模式要快得多。调试模式可以在您自己的代码中隐藏性能问题。

缓存

Use CompiledQuery.Compile() recursively avoiding recompilation of your query expressions Cache not-prone-to-change content using OutputCacheAttribute to save unnecessary and action executions Use cookies for frequently accessed non sensitive information Utilize ETags and expiration - Write your custom ActionResult methods if necessary Consider using the RouteName to organize your routes and then use it to generate your links, and try not to use the expression tree based ActionLink method. Consider implementing a route resolution caching strategy Put repetitive code inside your PartialViews, avoid render it xxxx times: if you end up calling the same partial 300 times in the same view, probably there is something wrong with that.

路由

使用Url。RouteUrl("User"， new {username = "joeuser"})指定路由。ASP。NET MVC性能由Rudi Benkovic编写 缓存路由解析使用这个助手UrlHelperCached ASP。NET MVC性能由Rudi Benkovic编写

安全

使用表单身份验证，将您经常访问的敏感数据保存在 身份验证票

DAL

当通过LINQ访问数据时，依赖于IQueryable 利用存储库模式 配置您的查询，即优步Profiler 考虑二级缓存，为你的查询添加一个范围和一个超时，即NHibernate二级缓存

负载平衡

利用反向代理，在应用实例中分散客户端负载。Stack Overflow使用HAProxy (MSDN)。 使用异步控制器来实现依赖于外部资源处理的操作。

客户端

Optimize your client side, use a tool like YSlow for suggestions to improve performance Use AJAX to update components of your UI, avoid a whole page update when possible. Consider implement a pub-sub architecture -i.e. Comet- for content delivery against reload based in timeouts. Move charting and graph generation logic to the client side if possible. Graph generation is a expensive activity. Deferring to the client side your server from an unnecessary burden, and allows you to work with graphs locally without make a new request (i.e. Flex charting, jqbargraph, MoreJqueryCharts). Use CDN's for scripts and media content to improve loading on the client side (i.e. Google CDN) Minify -Compile- your JavaScript in order to improve your script size Keep cookie size small, since cookies are sent to the server on every request. Consider using DNS and Link Prefetching when possible.

全局配置

If you use Razor, add the following code in your global.asax.cs, by default, Asp.Net MVC renders with an aspx engine and a razor engine. This only uses the RazorViewEngine. ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new RazorViewEngine()); Add gzip (HTTP compression) and static cache (images, css, ...) in your web.config <system.webServer> <urlCompression doDynamicCompression="true" doStaticCompression="true" dynamicCompressionBeforeCache="true"/> </system.webServer> Remove unused HTTP Modules Flush your HTML as soon as it is generated (in your web.config) and disable viewstate if you are not using it <pages buffer="true" enableViewState="false">

使用捆绑和缩小还可以帮助您提高性能。它基本上减少了页面加载时间。

Gzip实现。 对部分视图使用异步呈现。 最小化数据库命中次数。 使用编译后的查询。 运行分析器找出不必要的匹配。优化所有返回响应时间超过1秒的存储过程。 使用缓存。 使用捆绑最小化优化。 对只读内容使用会话缓存和本地存储等HTML 5实用程序。

我做了上面所有的答案，但还是没有解决我的问题。

最后，我解决了我的网站加载缓慢的问题，在发布配置文件PrecompileBeforePublish设置为真。如果你想使用msbuild，你可以使用这个参数:

 /p:PrecompileBeforePublish=true

这真的很有帮助。现在我的MVC ASP。NET加载速度快10倍。
