In this case the GC will consume the time. Do you can activate the GC logging? See http://java.sun.com/docs/hotspot/gc5.0/gc_tuning_5.html http://java.sun.com/docs/hotspot/gc5.0/gc_tuning_5.html for JVM options. Also you can use 'jstat', part of java distribution with Java6 I'm not sure whether standard for Java5, to analyse the GC behaviour. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/590061#590061] Start a new discussion in Performance Tuning at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
