This is crap. We're talking about a difference of 30 some milliseconds over a million+ iterations! In realistic terms, this is nothing.

Developers: raise a red flag when you see someone say "over x times faster/slower!" You've got to look at the actual numbers before doing anything with this information. If you execute your Sum method just once, you're not even going to be able to measure the distance.

Hmmm... the big companies seem to care about 1% performance improvements. Ask mozilla, apple, or microsoft whether they think 1% is important. Granted, writing it in C++ would be a lot better.
