[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1132) Locking optimization: reorder lock acquisition to avoid deadlocks

[Mircea Markus (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12603776#comment-12603776 ] 

Mircea Markus commented on ISPN-1132:
-------------------------------------

Re:weather or not this feature should be enabled by default: I tend to think yes, as it depends on another experimental feature being enabled - ISPN-1131. Guess a final decision can be made once the performance impact is also analyzed.

> As without ISPN-1131 locks are being acquired as the transaction progresses this optimization makes more sense after having ISPN-1131 in place.
