Tuning MVC3 application that uses jquery?

Question

I'm trying to tune up my MVC3 application that uses a lot of jquery libraries, including jqGrid.
I'd be interested to hear your best practices and performance tips and tricks if any. What you normally do for 'most' MVC3 based applications as a given.

Thank you

Description

If tune means better loading you can do these 3 things. You could optimize the loading time up to 80% with theese techniques.

I suggest to use Fiddler2 to see how your changes perform.

1. you should compress and combine your javascript files.
2. you should use the OutputCache Attribute if possible
3. you should remove unused ViewEngines

Sample

1. Combine/Compress/Minify JS and CSS files in ASP.NET MVC

2. MSDN: OutputCacheAttribute Class

   [OutputCache(Duration=60)]
   public ActionResult Index()
   {
       return View();
   }
   

3. do this in global.asax

   protected void Application_Start()
   {
       // other stuff
   
       ViewEngines.Engines.Clear();
   
       // if you only use RazorViewEngine
       ViewEngines.Engines.Add(new RazorViewEngine());
   
       // if you only use WebFormViewEngine
       ViewEngines.Engines.Add(new WebFormViewEngine());
   }

Combining and minifying your scripts is a great start to cut down the response size and number of requests. Also, be sure not to include uneccessary plugins and code that won't be used on particular pages...
