I am using JBoss 4.0.4.GA and JBossWS 1.0.2.GA. I am calling a Web Service using a JSR-109 client as defined in the userguide (http://labs.jboss.com/portal/jbossws/user-guide/en/html/clients.html#jsr1...). However, I am experiencing poor performance (average 400 milliseconds) when JBossWS is unmarshalling/deserializing the response. The response contains 4 Strings and 4 user types (which themselves contain booleans and Strings). The total size of the response is around 5600 bytes. Are there known issues with the unmarshalling/deserializing performance of JBossWS? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3967927#...
