Yeah profilers can look scary.

Here's a quick primer on Shark:
http://developer.apple.com/tools/sharkoptimize.html

Basically in XCode:
Debug -> Launch Using Performance Tool -> Shark

Click OK in the dialog that comes up and your app will start. Add a
new object and before you save in the app click 'Start' in the little
Shark window. Save in your app. Press Stop in the Shark window. You'll
get a screen full of info. In the Heavy (Bottom-Up) pane you'll the
methods that you spend the most time in. Choose one and you'll get a
Heaviest Path - that's the call stack that cost you the most time.
Poke around until you get a feel for whats going on.

Hope that helps a little,
Guy
