[jboss-remoting-issues] [JBoss JIRA] Commented: (JBREM-1277) Allow configuration of socket and bisocket accept thread priority

[Ron Sigal (JIRA)]

    [ https://issues.jboss.org/browse/JBREM-1277?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12589142#comment-12589142 ] 

Ron Sigal commented on JBREM-1277:
----------------------------------

SocketServerInvoker (and therefore SSLSocketServerInvoker, BisocketServerInvoker, and SSLBisocketServerInvoker) can now be configured with the "acceptThreadPriorityIncrement" parameter, by which the priority of the accept thread(s) is increased.  If the resulting priority is out of the acceptible range (java.lang.Thread.MIN_PRIORITY to java.lang.thread.MAX_PRIORITY), a warning is issued and the priority is not changed.

In the bisocket transport, the value of "acceptThreadPriorityIncrement" is used to increase the priority of the SecondaryServerSocketThread, which manages the secondary ServerSocket.

These changes have been applied to branches 2.2 and 2.x

Testing:  

  * org.jboss.test.remoting.transport.bisocket.accept.SecondaryAcceptThreadPriorityTestCase
  * org.jboss.test.remoting.transport.socket.accept.AcceptThreadPriorityTestCase

Waiting for results in hudson.

Need to update Remoting Guide and Users Guide.

> It is possible that under heavy load, the org.jboss.remoting.transport.socket.SocketServerInvoker accept thread and the org.jboss.remoting.transport.bisocket.BisocketServerInvoker secondary accept threads, which manage ServerSockets, can get starved by the worker threads.  It would be useful to be able increase the priority of these threads.
