If you need to find which part of your Umbraco application is slowing the site down, follow these steps:

1. Set the debug property of the compilation section of your Web.config to true: <compilation defaultLanguage=”c#” debug=”true” batch=”false” targetFramework=”4.5″>
   • If you’re using an older version of Umbraco, you also probably need to set the umbracoDebugMode app setting to true in the same config file: <add key=”umbracoDebugMode” value=”true” />
2. Add the query string ?umbdebug=true to your Umbraco page URL
3. Thats it!

It uses Mini Profiler, so you can add your own profile stops, but out-of-the-box it already analyses the time it takes to render each view.

Happy profiling!
