另外，如果你使用NHibernate，你可以为查询打开和设置二级缓存，并添加到查询范围和超时。并且有踢屁股的EF, L2S和NHibernate分析器- http://hibernatingrhinos.com/products/UberProf。这将有助于调优您的查询。

只是想说说我的意见。优化MVC应用程序中URL路由生成的最有效的方法是…根本不产生它们。

我们大多数人或多或少都知道url是如何在我们的应用程序中生成的，所以只要使用静态Url.Content(“~/Blahblah”)而不是Url.Action()或Url.RouteUrl()，就可以胜过所有其他方法近20倍甚至更多。

PS:我已经运行了几千次迭代的基准测试，如果有兴趣的话可以在我的博客上发布结果。

这不是一个惊天动地的优化，但我想我要把它扔在那里-使用CDN的jQuery，等等。

引用ScottGu自己的话:微软Ajax CDN使你能够显著提高ASP的性能。NET Web Forms和ASP。asp.net MVC应用程序使用ASP。NET AJAX或jQuery。这项服务是免费的，不需要任何注册，可以用于商业和非商业目的。

我们甚至使用CDN为我们的web部件在Moss使用jQuery。

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

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).

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。
