Better JGroups defaults ----------------------- Key: WFLY-1024 URL: https://issues.jboss.org/browse/WFLY-1024 Project: WildFly Issue Type: Enhancement Security Level: Public(Everyone can see) Components: Clustering Reporter: NadirX 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 AS7 protocol list (UDP): PING, MERGE2, FD_SOCK, FD, VERIFY_SUSPECT, BARRIER, pbcast.NAKACK, UNICAST2, pbcast.STABLE, pbcast.GMS, UFC, MFC, FRAG2, RSVP JDG protocol list (UDP): PING, MERGE2, FD_SOCK, FD_ALL, pbcast.NAKACK, UNICAST2, pbcast.STABLE, pbcast.GMS, UFC, MFC, FRAG2, RSVP AS7 protocol list (TCP): MPING, MERGE2, FD_SOCK, FD, VERIFY_SUSPECT, BARRIER, pbcast.NAKACK, UNICAST2, pbcast.STABLE, pbcast.GMS, UFC, MFC, FRAG2, RSVP JDG protocol list (TCP): MPING, MERGE2, FD_SOCK, FD, VERIFY_SUSPECT, pbcast.NAKACK, UNICAST2, pbcast.STABLE, pbcast.GMS, UFC, MFC, FRAG2, RSVP
