这似乎是显而易见的，但是在生产环境中以及在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。

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).

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。

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。

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

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。
