Worth the effort?

What effort? I would have used an array from the start, meaning it take extra effort to use the hash version. Besides, we're talking of a 5 character difference.

Compare that to the original implementation

Why? When benchmarking video cards, you don't compare them to a CGA video card, you compare them to each other.
