[jboss-jira] [JBoss JIRA] Commented: (JBTM-218) Contention on HashTable in com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.java
[ http://jira.jboss.com/jira/browse/JBTM-218?page=comments#action_12362617 ]
Mark Little commented on JBTM-218:
----------------------------------
Phillip, I'm not sure the tests I have on my laptop are able to show up much of a
difference. I've attached two more jars for you to try (jbossjta-ht.jar should be the
original jar, whereas jbossjta-sm.jar is one that uses a synchronized map). Let me know
what you see when you run your tests.

I'm seeing some contention on the object _transactions in the class
com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple. Most of the
contention happens in the getTransaction() method.
