Sitevision profiling

Sitevision has a feature which lets you view the rendering times of all the modules on the page. This feature is toggled by the query parameter profiling with the values true or false. The state is stored in your session, so you'll have to turn it off by yourself.

This bookmarklet toggles the query parameter for you.
