I like to use Rack-Mini-Profiler to see how my pages perform in a relatively non-obtrusive way.

The problem is sometimes it gets in the way of something I'm trying to look at.

To hide it temporarily you can do one of two things:

1) Press Alt+p to toggle it

OR

2) You can use url parameter ex. http://yoursite.com?pp=disable and change it to enable once your done.
