[jboss-jira] [JBoss JIRA] (AS7-4930) Better JGroups defaults

[Bela Ban (JIRA)]

    [ https://issues.jboss.org/browse/AS7-4930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12697607#comment-12697607 ] 

Bela Ban commented on AS7-4930:
-------------------------------

Note that JGroups' ergonomics will in the future try to adjust the min and max threads values according to load, number of cluster nodes, number of shared channels and so on. This feature wont be available if we use an injected thread pool.
Nothing to worry about for now, but maybe something to keep in mind in the future.

> 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
