ASP.NET MVC渲染似乎很慢 [英] ASP.NET MVC rendering seems slow

问题描述

我已经在Visual Studio中创建了一个全新的MVC4 Web应用程序，并且除了为其添加Home控制器和"Hello world"索引视图外，还没有做其他任何事情.然后，我安装了MiniProfiler NuGet软件包，并将必要的几行放在_Layout.cshtml中.当我以发布模式(在IIS中托管)运行网站时，这就是我得到的:

I've created a brand new MVC4 web application in Visual Studio, and done nothing more with it than add a Home controller and a "Hello world" index view for it. I then installed the MiniProfiler NuGet package and put the necessary couple of lines in _Layout.cshtml. This is what I get when I run the site in Release mode (hosted in IIS):

渲染时间因页面加载而异，但130ms差不多快了.这对我来说似乎有点慢，因为我看到其他人以30毫秒或更短的时间渲染页面.有什么主意为什么使用全新的空MVC4项目会如此缓慢地渲染?我的处理器是Intel Core i5-2400，该计算机具有16GB RAM.

The rendering time varies by pageload, but 130ms is about as fast as it gets. This seems a bit slow to me, as I've seen other people who get pages rendered in 30ms or quicker. Any ideas why the rendering would be this slow with a brand new empty MVC4 project? My processor is an Intel Core i5-2400 and the machine has 16GB RAM.

顺便说一句，这不是第一次加载页面.在获得此130ms的结果之前，我重新加载了页面几次.

By the way, this is not the first time the page is loaded; I reloaded the page a few times before getting this 130ms result.

更新:
我遵循了PSCoder的答案中的建议(删除了所有RazorViewEngine，但将其减少了一半):

UPDATE:
I followed the advice in the answer from PSCoder (remove all but the RazorViewEngine), and it halved the rendering time:

这确实很好，但是页面的主要Render操作仍能获得约70ms或更高的时间；理想情况下，我希望将其减半或更好.

This is really good, but I still get about 70ms or higher for the main Render action of the page; ideally I'd like to halve that or better.

具体来说，我想问一下:

Specifically, I'd like to ask:

• 此渲染时间似乎过慢还是在我的计算机上平均?
• 有什么办法可以加快速度吗?

推荐答案

这可以帮助改善与ASP.NET MVC相关的性能问题，您可以做的一项性能改进就是清除所有视图引擎并添加一个.您使用的.例如:-RazorViewEngine. MVC默认情况下会注册2个视图引擎Webforms和Razor视图引擎，因此清除并添加单独使用的视图引擎将提高查找性能.

This could help improve ASP.NET MVC related performance issue , one performance improvement that you can do is to clear all the view engines and add the one(s) that you use. say for ex:- RazorViewEngine. MVC registers 2 view engines by default Webforms and Razor view engines, so clearing and adding the ones that is used alone will improve the look up performance.

您可以在global.asax Application_Start中添加它.

You can add this in global.asax Application_Start.

        ViewEngines.Engines.Clear();    
        ViewEngines.Engines.Add(new RazorViewEngine());      

为了完全利用视图查找缓存，从而再次提高性能，请在发布模式下编译代码，并确保为web.config文件配置了<compilation debug="false" />以便可以启动视图查找缓存.

In order to completely utilize view look up caching and thus again performance gain compile the code in release mode and make sure that your web.config file is configured with <compilation debug="false" /> for view look up caching to kick in.
