Stop Asking 1 Millisecond Questions

Over the holiday, I was doing some year-end financial reviews. One of my favorite voices in personal finance is Ramit Sethi. He has a concept of a "$3 dollar question" - a personal finance question that gets a lot of media coverage or attention, but really matters very little to actual financial well-being. A classic example is worrying about interest rates on savings accounts - even in a high-interest environment, which we haven't had in years, moving checking accounts around to chase the latest interest rate promotions is a good way to waste hours chasing $10 in lifetime returns.I thought this concept applied quite well to a lot of the questions I get around web application performance. Are you asking a question that will improve your critical performance metrics by a millisecond, or by 3000 milliseconds?.
