That's rather pointless. Unless you know exactly what you're testing (e.g. 
rendering this very specific path on top of this very specific background) it's 
going to be wrong anyway. Of course you could use some real world app that 
uses both Cairo and Qt, e.g. WebKit or Poppler with trace frameworks they both 
come with (cairo-trace and qttracereplay) to compare how they perform 
rendering specific pages but you'll have to assume that the implementations of 
both are 100% correct and optimal (which they never are, so you're starting 
from a fallacy no matter what).

Also qgraphicsview is a canvas that uses Arthur (i.e. QPainter) for rendering, 
you can't really compare that to Cairo.
