Tuning JBoss 5 Performance

In a default installation of JBoss 5, the JBoss hot deployment scanner runs every 5 seconds, which affects JBoss performance. You can disable this feature, if it is not needed, or change how often it runs.

To disable or modify hot deployment

1. Edit the hdscanner-jboss-beans.xml in this location:

   Single Node: jboss_home/server/default/deploy

   Cluster: jboss_home/server/all/deploy

2. To disable this feature, add the following line inside the HDScanner bean:

   <attribute name="ScanEnabled">False</attribute>
   

3. To modify the scan frequency, increase the scanPeriod attribute value above 5000 (milliseconds).

To address Out of Memory errors

You may see "Out of Memory" exceptions if the Java Heap size is too small. We recommend an initial size of 1024.
