Fair enough

"But you fail to say how big the main array is? "

not that big, the size of the main array is 3000. n is 500-1000 (the number of inner arrays from which i need to pick)

"Or what you need to look up. Ie. what do you start with; and what information do you need to end up with?"

i start with my query array which is 500-1000 different ints between 0 and 2999 and i need to end up with the int value from inner arrays that is the most prevalent on those picked 500-1000 arrays. (intersect that has the highest number of elements)

"Or how many lookups you need to do? "

about 15000000 per hour.
