scootstah Posted February 9, 2012 Share Posted February 9, 2012 If you spend too much time trying to optimize code before it is written, you are likely wasting time. If you feel your application is too slow afterwards, you can profile it and attempt to pin-point where the slowness is coming from and then you can try to optimize it. Learn how to normalize the database and make sure your queries are efficient (like using joins over sub-selects, not looping queries, not using multiple queries when you could have used a single query, etc).
