public class Loop

extends java.lang.Object

Computing the sum over all x[i]*x[j], i,j=0,...,N-1 in two different loops which do exactly the same operations just accessing the array elements in different order. Why are the relative speeds of the loops so dramatically dependent on N when N is so small the array fits in the L1 data cache???
