There are major pitfalls. Statistics is hard. For example, you might remember, recently I posted "quick survey" of hash functions. My point was that djb performed a bit better than jenkins. I've made another attempt just recently. You know what. Jenkins handle sparse sets a lot better than djb. It's only about very dense sets that djb might be a bit advantageous. So, things might grow complicated, really. Of course, that's not your fault. And I'm not trying to make them complicated, either. That's just what things really are.-( Anyway, when someone tells you he's got one percent an improvement. The right thing to do is to ask, are you a major in statistical physics?
