Javassist: ~24.5s Introspection: ~21s I need to profile this, but think this is because when configuring beans, we normally only set properties once, so we get the overhead of creating the class, but not the benefit of invoking it lots of times. I will ask Chiba if there is anything that can be done to JavassistMembersFactory to make this faster. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/537449#537449] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
