Not to counter the main argument but CPU loves it some predictable patterns as well. pattern like the one below will execute up to 10 times faster if array is sorted due to data locality and branch prediction sum: float a: float array[some_huge_number] fill_array(a, random(1)) for f in a if a[i]>0.5 sum=sum+f
