JBoss development, A new message was posted in the thread "Profiling the dependency project": http://community.jboss.org/message/525176#525176 Author : Kabir Khan Profile : http://community.jboss.org/people/kabir.khan@jboss.com Message: -------------------------------------------------------------- We do quite a lot of adding to and removing from AbstractController.installed and the sets stored in AbstractController.contextsByState. They are currently implemented as CopyOnWriteArraySets which perform badly when there are large numbers of entries in the sets already. I tried replacing these with ConcurrentSet (based on ConcurrentHashMap), but that performed worse. I've spoken to Jason who gave me a few ideas, but will put those off until I've picked off a few other things. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/525176#525176
