There are 2 problems here; first I was using CGContextFlush instead of 
CGContextSynchronize,  this was causing 20000ticks/draw of overhead 
(this is now fixed in SVN), the second is the cairo backend sucking and 
causing crappy performance.  I dont have any immediate fix for this 
(until the backend is fixed; this will stay)
