Hi, sorry for the crossposting but I wrote about a performance issue concerning CMP in the persistance forum which might not have been the correct place. The thread can be found at http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= be grateful if someone have any useful tips of what might cause this behaviour or if this simply is what is to be expected from CMP. /Sverker
