It's often true too that trying to eke performance out of something necessarily makes the code more difficult, right? Because you are going closer to the middle or doing these kinds of hoop jumping that doesn't really result in clear code. Another thing to think about, I guess, is test data versus real data. You know, how many times have there been website launches where, oh, it seemed like it was fine, but now it's down because there are actually more than 10 rows in the database and they forgot to put indexes.
