I've produced a new script that reproduces the view regression. I apologize in advance for exposing my awful Bash scripting abilities (also my inability to write "pure" shell. Your "Bashism" is my "it works").
I get 0m56.521s for 1.1.x and 1m17.108s for 1.2.x. That is, 1.1.x complete the same task in only 72% of the time that 1.2.x takes. http://friendpaste.com/UI1OcECLEzR6i4D75LqQy It would be very useful if others could reproduce (or contradict!) this finding.
