Manik Surtani updated ISPN-1284:
--------------------------------

        Summary: Use synchronizations as a default transactional mode rather than XA  (was: change default tx enlistment)
    Description: 
Transactions are being enlisted as XAResources with recovery disabled by default.

XAResource enlistment *without* recovery does not bring any benefit over Synchronization enlistment, which is more efficient(30-40%).  See http://infinispan.blogspot.com/2011/06/transactions-enhancements-in-50.html

So the suggested enlistment should be Synchronization (default). Also if xa-enlistment is preferred then recovery should be enabled by default - there's little reason in using XAResource enlistment without recovery.
