ASP.NET MVC Performance Tips

In this we will discuss about how can we increase the performance of website that using ASP.NET MVC.

1.   Remove Unused view engines

protected void Application_Start() 
{ 
    ViewEngines.Engines.Clear(); 
    ViewEngines.Engines.Add(new RazorViewEngine()); 
}

2. Deploying Production Code in Release Mode

Make sure your production application always runs in release mode in the web.config

<compilation debug=”false”></compilation>

<configuration> <system.web> <deployment retail=”true”></deployment> </system.web> </configuration>

3. Use OutputCacheAttribute when appropriate

MVC will not do any View Look-up Caching if you are running your application in Debug Mode

[OutputCache(VaryByParam = "none", Duration = 3600)]
public ActionResult Categories() 
{ 
    return View(new Categories()); 
}

 4. Use HTTP Compression

Add gzip (HTTP compression) and static cache (images, css, …) in your web.config

<system.webserver><urlcompression dodynamiccompression=”true” dostaticcompression=”true” dynamiccompressionbeforecache=”true”></urlcompression> </system.webserver>

5. Avoid passing null models to views
6. Remove unused HTTP Modules
7. ASP.NET MVC ACTION FILTER – CACHING AND COMPRESSION
Source: ASP.NET MVC ACTION FILTER – CACHING AND COMPRESSION
8. Un controlled actions
9. Put repetitive code inside your PartialViews

10. Add an Expires or a Cache-Control Header

<configuration><system.webServer> <staticContent> <clientCache cacheControlMode=”UseExpires” httpExpires=”Mon, 06 May 2013 00:00:00 GMT” /> </staticContent> </system.webServer> </configuration>

11. Un controlled actions

protected override void HandleUnknownAction(string actionName)
{
       RedirectToAction("Index").ExecuteResult(this.ControllerContext);
}
