Jencks perfomance tuning

[Eugene Prokopiev]

Hi,

Where can I read about Jencks perfomance tuning? For example, I have 
this configuration:

<beans>

        <!-- Geronimo Transaction Manager -->
	<bean id="transactionContextManager" 
class="org.jencks.factory.TransactionContextManagerFactoryBean"/>
	<bean id="geronimo" 
class="org.jencks.factory.GeronimoTransactionManagerFactoryBean"/>
	<bean id="geronimoTransactionManager" 
class="org.springframework.transaction.jta.JtaTransactionManager">
                <property name="userTransaction" ref="geronimo" />
        </bean>

        <!-- ActiveMQ Broker configuration -->
	<bean id="broker" class="org.apache.activemq.broker.BrokerService" 
init-method="start" destroy-method="stop">
                <property name="persistent" value="false"/>
                <property name="transportConnectorURIs">
                        <list>
                                <value>tcp://localhost:5000</value>
                                <value>vm://localhost</value>
                        </list>
                </property>
        </bean>
        
        <!-- Jencks Connection Manager configuration -->

</beans>

Need I change it anyway to get the best perfomance? Need I make some 
changes in java command line for starting up JVM? Need I consider my OS 
or hardware for setting params? My OS is Linux (kernel 2.6.16). My 
hardware is 1G RAM and 2 Xeon 3GHz with hyper-threading turned on. There 
are no any other applications will be run on this machine except spring 
context above.
