Would using IIS instead of IIS Express speed up the start time for VS2013 WebAP application running locally?

Question

I am using VS2013 and the Microsoft WebAPI. WHen I start up my application it spends a lot of time doing things such as the following:

'iisexpress.exe' (CLR v4.0.30319: /LM/W3SVC/1273337584/ROOT-1-130406535805395435): Loaded 'C:\Windows\Microsoft.Net\assembly\GAC_MSIL\System.Web.ApplicationServices\v4.0_4.0.0.0__31bf3856ad364e35\System.Web.ApplicationServices.dll'.

Is there any possible way that I could speed this up? For example would it be faster if I was to have IIS running and use that?

Note this is slightly similar to

Exceedingly long compile time for Entity Framework project

However this question was not properly answerd so it's no help to me.

Answer 1

IIS vs IIS Express probably won't help your application startup time. But reading this output leads me to believe you're running the entire application in debug mode. Debugging is VERY slow. I would start by running the application without a debugger attached, and ensure debug="true" is not set in the web.config.

Answer 2

Just wondered the same and tried for an application I have. Switching from from IIS Express to Local IIS actually slowed it down by a couple seconds. I am also using debug configuration (on purpose).
