You can save jboss start time by commenting everything in the deployers\jsf.deployer\META-INF\jsf-integration-deployer-jboss-beans.xml.
just keep following lines.
<?xml version="1.0" encoding="UTF-8"?>
<!--
JBoss JSF + JBossAS integration
-->
<deployment xmlns="urn:jboss:bean-deployer:2.0">
JBoss JSF + JBossAS integration
-->
<deployment xmlns="urn:jboss:bean-deployer:2.0">
</deployment>
This will save lot of time jboss uses in JSF initialization.
Thanks!!
