             Summary: Better JGroups defaults
                 Key: AS7-4930
                 URL: https://issues.jboss.org/browse/AS7-4930
             Project: Application Server 7
          Issue Type: Enhancement
          Components: Clustering
    Affects Versions: 7.1.2.Final (EAP)
            Reporter: Tristan Tarrant
            Assignee: Paul Ferraro


The JGroups subsystem needs optimal defaults out of the box, that are also good for derived products (e.g. JDG), both for protocols and thread pools.

Use a bounded thread pool for the default executor
core-size==number of members (32 for JDG)
max-threads = 1.5*core-size

oob should be queueless
