Chapter 14. Performance tuning on
distributed environments
Performance tuning is a complex task that spans multiple components and areas with a goal
of improving system performance. It is heavily dependent on application architecture, system
infrastructure, and the amount of load on your system. WebSphere Application Server V8.5
delivers a scalable and highly available platform for applications and provides multiple
methods for tuning options to optimize runtime performance.
This chapter provides information about methods and provides a list of tunable parameters by
which you can improve performance. WebSphere provides an extensive number of tunable
parameters. We include those parameters that might have the most noticeable benefits for
your system. We use the queue analogy to represent WebSphere resource pools and provide
a methodological approach to tuning these pools. We also include methods to tune Java
virtual machines (JVM) and other various components.
This chapter includes the following topics:
