In this chapter, you've seen 20 hot-list items that I consider to be low-hanging fruit (i.e., easy, low risk, and quick win) when it comes to well-performing and well-scaled application development. As I noted at the beginning of the chapter, there are thousands of best practices and recommended approaches for Java/J2EE application development. That said, the 20 items I covered in this chapter will provide you with a good starting point and serve as a checklist for your performance management. Your mileage may vary with each item, so be sure to study each in detail before you implement it.
