I ran assistant in Shark (the profiler included with Xcode) and the 
slowness is not in anything tied to the unified title and toolbar. It's 
more to do with laying out the web page. On large pages (like 
qwidget.html) this becomes  slow.

Speeding up these large layouts is something we need to look at and 
solve, but it does show that it has nothing to do with the 
setUnifiedTitleAndToolBarOnMac value. I ran assistant with it both on 
and off and experienced the same result.
