[jboss-jira] [JBoss JIRA] Reopened: (JBTM-218) Contention on HashTable in com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.java
[ http://jira.jboss.com/jira/browse/JBTM-218?page=all ]
Phillip Thurmond reopened JBTM-218:
-----------------------------------
Sorry Mark, I mis-typed. I meant to say that the object should probably be changed to
ConcurrentHashMap. Whenever a hashtable is accessed, the whole object must be locked.
Using ConcurrentHashMap, only a portion of the object is locked, so the contention will be
reduced.

I'm seeing some contention on the object _transactions in the class
