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。

当通过LINQ访问数据依赖IQueryable…

为什么使用AsQueryable()而不是List()?

．.． 并利用一个好的存储库模式:

在存储库模式中加载子记录

这将优化数据访问，以确保只加载需要的数据。

在您嚷嚷着优化客户端时，不要忘记数据库层。我们有一个应用程序在一夜之间从5秒加载到50秒。

在检查中，我们做了一大堆模式更改。一旦我们刷新统计数据，它突然变得像以前一样灵敏。

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。

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).
