Introducing Performance Tuning and Optimization
Jeffrey Hasan, Kenneth Tu · Apress eBooks · 2003
The purpose of this chapter is to provide you with a primer on the concepts and terminology of application performance and optimization. For many of you, these are concepts that are familiar, but with which you are not necessarily comfortable. Application performance issues are often paid little attention in smaller Web applications with low hit counts. However, these issues start to feel more important as your application starts experiencing higher hit counts and heavier loads. It is an unfortunate reality that application performance behaves in a non-linear way. To borrow a phrase from the stock market, this means that current (application) performance is not an indicator of future results. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
