[Mircea Markus (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12650941#comment-12650941 ] 

Mircea Markus commented on ISPN-1615:
-------------------------------------

removing the tx code causes the PFER not to be atomic: i.e. the put might happen on some nodes and might not happen on some other nodes. If users can live with that then they should enable use1PcForAutoCommitTransactions which has the same effect:speed(1PC) at the cost of potential inconsistencies.

> The main reason for suspending the transaction was to avoid failures impacting the result of the transaction.
> However, ever since ISPN-1556 has been implemented, any FAIL_SILENT operation (like PFER) won't have an impact on the transaction if it fails, so this transaction suspension is not really needed.
> Removing the suspension code is apparently a performance booster in 2LC.
