Controlling Your Code's Speed
Don't write unnecessarily fast code. What I mean here is that you shouldn't produce fast code when you don't need to-you'll probably be wasting time. Code to the requirement. If it must be fast, take that into account as you code-not after. If it's OK to be slow(er), then again, code to the requirement. For example, you might decide to use nothing but Variants if neither size nor execution speed is important. Such a decision would simplify the code somewhat, possibly improving your delivery schedule. Keep in mind that each project has different requirements: code to them!
