I downvoted this node because I think it is an inappropriate suggestion. Rule #1 of benchmarking is don't guess. Rule #2 of benchmarking is optimize what really matters.

The biggest potential problem I can see with this code (without seeing the data set) is that the loop tends to O(n/2) performance. If there are a lot of numbers in the array, it will take a while to find the right number. A hash lookup, tending to O(1) performance, would be much more performant.
