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。

Code Climber和这篇博客文章提供了提高应用程序性能的详细方法。

编译后的查询将提高应用程序的性能，但它与ASP没有任何共同之处。净MVC。它将加速每一个db应用程序，所以它不是真正的MVC。

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. Explanation And Benchmarks

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">

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。

1:获取时间。在你知道放缓在哪里之前，这个问题太宽泛了，无法回答。我正在做的一个项目就有这样的问题;没有日志记录，甚至不知道某些事情需要多长时间;在我们将计时添加到项目中之前，我们只能猜测应用程序的慢部分。

2:如果你有顺序操作，不要害怕轻度多线程。特别是当涉及到阻塞操作时。PLINQ是你的朋友。

3:在发布时预生成MVC视图这将有助于一些“第一页点击”

4:有些人认为存储过程/ADO在速度上有优势。其他人则主张加快英孚教育的发展速度，并对教育层级及其目的进行更明确的划分。我曾见过SQL和使用scpros /Views进行数据检索和存储的变通方法时非常缓慢的设计。同时，你的测试难度也会增加。我们目前正在从ADO转换到EF的代码库的性能并不比旧的手卷模型差(在某些情况下更好)。

5:也就是说，考虑一下应用程序的预热。我们所做的帮助消除大部分EF性能问题的部分工作是添加一个特殊的预热方法。它不预编译任何查询或任何东西，但它有助于大量元数据的加载/生成。在处理Code First模型时，这一点可能更加重要。

6: As others have said, Don't use Session state or ViewState if possible. They are not necessarily performance optimizations that developers think about, but once you start writing more complex web applications, you want responsiveness. Session state precludes this. Imagine a long running query. You decide to open a new window and try a less complex one. Well, you may as well have waited with session state on, because the server will wait until the first request is done before moving to the next one for that session.

7:最小化到数据库的往返。保存你经常使用但实际上不会更改到. net缓存的东西。在可能的情况下尝试批处理插入/更新。

7.1:避免数据访问代码在你的Razor视图没有一个该死的好理由。要不是亲眼所见，我也不会这么说。在构建模型时，他们已经在访问数据了，为什么他们不把数据包括在模型中呢?

我还要补充一点:

Use Sprites: Sprites are a great thing to reduce a request. You merge all your images into a single one and use CSS to get to good part of the sprite. Microsoft provides a good library to do it: Sprite and Image Optimization Preview 4. Cache Your server object: If you have some references lists or data which will change rarely, you can cache them into memory instead of querying database every time. Use ADO.NET instead of Entity Framework: EF4 or EF5 are great to reduce development time, but it will be painful to optimize. It's more simple to optimize a stored procedure than Entity Framework. So you should use store procedures as much as possible. Dapper provides a simple way to query and map SQL with very good performance. Cache Page or partial page: MVC provides some easy filter to cache page according to some parameters, so use it. Reduce Database calls: You can create a unique database request that returns multiple objects. Check on Dapper website. Always have a clean architecture: Have a clean n-tiers architecture, even on a small project. It will help you to keep your code clean, and it will be easier to optimize it if needed. You can take a look at this template "Neos-SDI MVC Template" which will create a clean architecture for you with lots of performance improvements by default (check MvcTemplate website).
