Poor performance and slow website using MVC 5 attribute routing

Question

I am developing a site on Azure, with mvc5. I use attribute routing, with routes and route prefix on controllers. I am calling with the action.link helper. I did not name my routes.

I did the following on my route.config:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapMvcAttributeRoutes(); routes.LowercaseUrls = true; routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); 

My controllers:

 [OutputCache(Duration = 600, Location = System.Web.UI.OutputCacheLocation.Client)] [RoutePrefix("istanbul/kadikoy")] [Route("{action=index}")] public class KadikoyController : Controller { public ActionResult Index() { return View(); } [Route("kadikoy-tarihi")] public ActionResult KadikoyTarihi() 

I have very low performance since the server response time, i.e. 9.6 s

If I comment on the attributes of the routing codes with default routing, I have a server response time of 2.1 s.

Thank you for your responses.

It turns out that the really expensive bit of this operation does not display your attribute routes, this is before it happens. MVC needs to create a ControllerFactory and get all types of controllers. This process is 1245 ms in my project, and the rest of the MapMvcAttributeRoutes () functions take about 45 ms. I assume that if you do not use attribute routing, controllers will be found as needed, and not immediately.
