The Application The application has the largest impact on performance. Inefficient code that nobody noticed on dedicated hardware WebSphere Application Server Performance Tuning Toolkit can help you accomplish this task. Overview The tool collects performance data from a JMX, from the PMI (performance monitoring Interface, performance monitoring interface) of the WebSphere application Server, and then presents a plain picture to the user There are a number of charts and tables to locate bottlenecks and to properly tune them. All guide sources come from well-documented IBM or IBM partner’s reference material.

IBM WebSphere Support provides a script called linperf.sh as part of the document, "MustGather: Performance, hang, or high CPU issues with WebSphere Application Server on Linux" (similar scripts exist for other operating systems). This script should be pre-installed on all machines where you run WAS and it should be run when you have
