如果您正在运行您的ASP。NET MVC应用程序在Microsoft Azure (IaaS或PaaS)上，然后至少在第一次部署之前执行以下操作。

Scan your code with static code analyzer for any type of code debt, duplication, complexity and for security. Always enable the Application Insight, and monitor the performance, browsers, and analytics frequently to find the real-time issues in the application. Implement Azure Redis Cache for static and less frequent change data like Images, assets, common layouts etc. Always rely on APM (Application Performance Management) tools provided by Azure. See application map frequently to investigate the communication performance between internal parts of the application. Monitor Database/VM performance too. Use Load Balancer (Horizontal Scale) if required and within the budget. If your application has the target audience all over the globe, then use Azure Trafic Manager to automatically handle the incoming request and divert it to the most available application instance. Try to automate the performance monitoring by writing the alerts based on low performance.

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。

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).

一件非常简单的事情是在访问页面所需的数据时进行异步思考。无论是从web服务、文件、数据库还是其他东西读取，都尽可能使用异步模型。虽然它不一定会帮助任何一个页面更快，但它会帮助您的服务器整体性能更好。

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。

以下是要做的事情

内核模式缓存 管道模式 移除未使用的模块 runAllManagedModulesForAllRequests 不要使用wwwroot 删除未使用的视图引擎和语言
