Tuning CWA
Overview
This chapter covers the tasks you can use to tune CWA performance:
Configuration and Tuning
This section will walk you through how to tune the application (either Master or Client Manager) to get better
performance.
performance.
Memory
These parameters tune the amount of memory the application has to use to get work done. If an application does not
have enough memory to work with, it could have very poor performance or in the worst case get out of memory errors
and fail.
have enough memory to work with, it could have very poor performance or in the worst case get out of memory errors
and fail.
The following parameters apply to all Java applications:
-Xmn = size of young generation (1/4 size of heap)
-Xmx = max heap size
-Xms = initial heap size (guarantees JVM has that much memory)
-Xss = thread stack size (increase if getting stack overflow exceptions)
JVMARGS= -Xmn1024m -Xms28672m -Xmx28672m
CPU
The system CPU is not readily tunable from our application or the JVM itself, however, know that the CPU is an important
resource that directly impacts performance. If a system does not have enough CPUs or CPU power, applications can run
very slowly across the board. Upgrade your system to more CPUs or faster CPUs if the system monitor consistently
shows the CPU meter very high.
