I think we should also consider replacing:

    <!-- Limit JBoss categories
    <category name="org.jboss">
       <priority value="INFO"/>
    </category>
    -->

with

    <!-- Limit JBoss categories to the threshold level for FILE appender -->
    <category name="org.jboss">
       <priority value="${jboss.server.log.threshold}"/>
    </category>

I was working with some clustering perf testing yesterday, and with EAP 
4.3 I found:

FILE appender threshold=INFO, org.jboss category=INFO == 5.694 req/sec
FILE appender threshold=INFO, org.jboss category=commented out = 4,205 
req/sec

Unscientific sample, YMMV, etc. I'm busy sorting some issues w/ AS 5 so 
don't have comparable figures for it, but I don't see why the basic 
pattern would be different.
