Oracle Performance Tuning and Optimization
Presentation PerformanceBecause many of these new client/server applications involve audio and video presentation, you should check whether you have inefficiencies in these presentation services. A graphics adapter that is too slow may be the cause of performance bottlenecks in video presentations. Many adapters can handle high resolutions and many colors but at a loss of performance. This may be a bottleneck for you. Client Hardware PerformanceSeveral components of the client hardware may be the cause of a performance bottleneck:
Any of these conditions can cause a bottleneck. However, the most common cause for performance problems on the client machine is the application. SummaryThis chapter began analyzing the client system and what could cause performance problems in it. It started out by defining what a client system is and reviewed the history of RDBMS applications and how they evolved into what we know as client/server computing. The chapter also introduced what I believe to be the next step in the evolution of client/server computing: the three-tiered client/server model. Then the chapter looked at possible areas of client bottlenecks and a few ways to determine whether you are having problems in those particular areas. In debugging problems on the client, you frequently find that the client application is at fault because of inefficient SQL statements or problems in data processing. Be sure that your client hardware has sufficient CPU and memory horsepower to handle sophisticated applications. With todays client machines, if you have enough memory, you should be able to achieve a good level of performance.
