In general, the goal of performance tuning is to increase throughput, reduce response times, and increase the capacity for concurrent requests, all balanced against costs. However, the response time increases proportionally to the user load.
Also, the performance advisors page can provide advice on tuning a production system under a real or simulated load.Workload distribution can affect performance when some resources are underutilized and others are overloaded.It is always important to consider what happens when some part of a cluster crashes. We recommend prioritizing work into short term (high), 3 months (medium) and long term (low).How the work is prioritized depends on the business requirements and where the most pain is being felt.IBM Rational and other companies have tools to perform code profiling.
An analysis of the application might reveal areas where some work might be reduced for some types of transactions.Guide yourself primarily with tools and methodologies. For example, with a typical Web Sphere Application Server application, start with the operating system, then Java, then WAS, then the application, etc.Gather data, analyze it, create hypotheses, and test your hypotheses. The following are some example scenarios and approaches (https://com/support/knowledgecenter/SSAW57_8.5.5/doc/ae/tprf_troubleshoot.html).Simply double-click the downloaded file to install it.Update Star Free and Update Star Premium come with the same installer.DON'T PANIC The Hitchhiker's Guide to the Galaxy, Douglas Adams Great, kid. Han Solo, Star Wars The Web Sphere Application Server Performance Cookbook covers performance tuning for Web Sphere Application Server (WAS), although there is also a very strong focus on Java, Operating Systems, and theory which can be applied to other products and environments.
