I'm not sure if there's anything built-in.

You can use http://www.david-tec.com/2015/02/episerver-debugging-tools/ and ShowTimeMeters to get startup times.

When debugging applications, I usually use dotTrace profiler for back-end stuff, and Google Chrome Dev Tools for front-end stuff.

You can also use Glimpse on your site (it's an awesome tool). This blog describes how you need to configure it on an EPiServer site:

Thanks for the responses.  This is probably a very newby question, but what does the "<episerverUI>" refer to in "/<episerverUI>/Shell/Debug/ShowTimeMeters"?  Is this the "/EPiServer/CMS/", the Page I want to look at or some other path?  

 - Thanks!  :)

Hello Dan the "EPiServerUI" refers to the URL segment for EPiServer. So in your case its "/EPiServer" and the URL you need is "/episerver/Shell/Debug/ShowTimeMeters"

http://localhost:12345/episerver/shell/debug/showtimemeters

Just replace 12345 with your port number

Thanks, but this does not apear to work on mine.  trying the URL, it takes me back to a default page, and the internal log returns:

... 404 Error: /Shell/Debug/ShowTimeMeters

... the controller for path '/Shell/Debug/ShowTimeMeters' was not found or does not impliment IController. 

Is there something I'm supposed to have installed to look up things like ShowTimeMeters?  Do I need a minimum version?  I believe I'm running 7.11.0.0

 - Thanks.

(message corrected, but Edit/delete reply does not appear to be working now)

Hello Dan

You need to ensure you are logged in, in the administrators group and have the following in your web.config/appConfig.config:

<configuration>
  <appSettings>
    <add key="EPi.DebugView.Enabled" value="true" />
  </appSettings>
</configuration>
