This was with 100,000 arrays each with 1,000 values. Of course the loop iterates through the entire loop which is needed to find all matches. If only one match is needed then you can just break out of the loop to save time. If we assume that half of the matches will be in the lower 500 and half in the upper then we can half the time for the loop but it is still 325 seconds.
