The premise is probably if you can optimize the code to be small, you are probably also optimizing how it runs too. Rather then just bloat up everything
Once you start optimizing for one aspect, others become less important. In this case, they are doing a few hacks to get to 2.5kb, which do impact runtime performance. A few users report it using 500mb at runtime due to the compression :/
Well that sucks, although I assume that's way better than the AI bloated version that now comes with Windows.
