It would be interesting to see these shark traces attached to a  
Radar.  I've certainly heard very few complaints about "Cocoa being  
slow", particularly given that "Cocoa" is an umbrella term for a  
pretty large grab bag of technologies.  Is it CoreGraphics which is  
slow?  The performance of one or more AppKit UI elements? Some of  
other [set of] API?  In any and all cases, the more detail the  
better.  Thanks!
