I reduced the VF to 8 & made relevant changes to show the same intended impact. 
I forced a VF because otherwise the vectorization threshold will come into play, adding one more configuration option. For a VF smaller than 8, I'll have to tune other parameters like small-loop-cost to make these tests show the IC computation without getting blocked earlier.
