[ https://issues.jboss.org/browse/JGRP-1980?page=com.atlassian.jira.plugin.... ] Sanne Grinovero commented on JGRP-1980: --------------------------------------- This was identified by using the JMH test I shared with you. To clarify: I didn't mean to suggest that the two methods _decrementIfEnoughCredits_ and _decrementAndGet_ are contending among each other. Just that both are showing contention. Given your explanation, I guess it's possible that many invocations of _decrementIfEnoughCredits_ are contending among each other. And similarly for the other method. The contention was quite low though, so I wouldn't consider this a priority at this point. It might become more relevant though if we managed to speed-up other areas.. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
