如何提高ASP ?NET MVC应用程序性能?

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。

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.

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).

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。
