Performance Tuning for DevTest VSE

Products

• CA Application Test
• Service Virtualization

Issue/Introduction

This document contains some properties that helped to improve the VSE performance with DevTest for basic service virtualization.

Environment

All supported DevTest releases and platforms.

Cause

N/A

Resolution

In the VSE server, edit the local.properties file and add the following properties:

lisa.vse.performance.enabled=true
lisa.pathfinder.on=false
vse.socket.reuse=true
lisa.net.timeout.ms=60000
lisa.net.xstream=false
lisa.dcm.maxExpandPerLoadChange=50
lisa.jpm.MaxInstances=5000
lisa.jpm.unlimited=false
lisa.overloadThreshold=30000
lisa.eventPool.maxQueueSize=65535
lisa.eclipselink.cache.timeout.ms=3600000
lisa.CycleExecHistory.buffer.size=2

Save the modified properties file and restart the VSE.

The number one performance constraint is the VSE and client-side logging setup. Under high load, logging can significantly slow performance.

The logging setup is controlled in $LISA_HOME/logging.properties.

The recommended logging.properties configuration for performance environment is WARN, ERROR or OFF:

In the VSE server, open the logging.properties file and modify the following properties:

From: log4j.rootCategory=INFO,A1 
To: log4j.rootCategory=WARN,A1

and 

From: log4j.logger.VSE=INFO, VSEAPP 
To: log4j.logger.VSE=WARN, VSEAPP
