Issue/Introduction

This document contains some properties that helped to improve the VSE performance with DevTest 10.x for basic service virtualization.

Environment

DevTest on release 10.x

Resolution

WIP

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.logger.com.itko=INFO 
To: log4j.logger.com.itko=WARN


and 


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