Improving client-side performance
Tuning software to achieve maximum performance is not an easy task. You must commit to producing efficient implementations and monitor software performance continuously during the software development process.
Employ the following general guidelines when you test applications for performance, such as using the getTimer() method and checking initialization time.
Before you begin actual testing, you should understand some of the influences that client settings can have on performance testing. For more information, see Configuring the client environment.
