[Thomas Fromm (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-2392?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Fromm updated ISPN-2392:
-------------------------------

    Description: 
Situation: REPL_SYNC cache, non transactional, locking isolation level NONE
Problem: when multiple threads trying to write same key on multiple nodes, the operation ends up mostly in locking timeouts

Mircea mentioned that the locking behaviour for non-tx caches could be optimized as well as for tx-caches or use the same mechanisms.
(One single lock, independed number of owners)
