[jboss-jira] [JBoss JIRA] Commented: (JBTM-216) Contention on Vector _threadSetups in ThreadActionData.java

Thu May 10 01:51:52 EDT 2007

    [ http://jira.jboss.com/jira/browse/JBTM-216?page=comments#action_12361955 ] 

Mark Little commented on JBTM-216:
----------------------------------

 If you're seeing the overhead on the data structure rather than the instances of what it contains, then the best we can probably do here is look at changing the data structure (maybe). The list of elements within the current structure needs to be called every time a thread requests a reference to its current transaction because of corba portable interceptors. This is specific to JTS: in the local JTA this vector will be zero size (typically). JTS will always be slower than local JTA for a number of reasons.
