             Summary: Improve throughput under contention for FlowControl.Credit
                 Key: JGRP-1980
                 URL: https://issues.jboss.org/browse/JGRP-1980
             Project: JGroups
          Issue Type: Enhancement
    Affects Versions: 3.6.6
            Reporter: Sanne Grinovero
            Assignee: Bela Ban


The methods {{org.jgroups.protocols.FlowControl.Credit.decrementIfEnoughCredits(long, long)}} and {{org.jgroups.protocols.FlowControl.Credit.decrementAndGet(long)}} are contending the locks on class synchronization when stress testing JGroups.

Wondering if we can think of polishing the implementation, although it looks like challenging.
