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
Fix For: 3.6.8
Attachments: bla.java
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.
