[jboss-jira] [JBoss JIRA] (JGRP-2482) Check if the largest thread pool is cluster-size + delta

[Bela Ban (Jira)]

    [ https://issues.redhat.com/browse/JGRP-2482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14138712#comment-14138712 ] 

Bela Ban commented on JGRP-2482:
--------------------------------

Hmm, it seems that the internal thread pool is only used if the regular thread pool is full and the message is tagged as {{INTERNAL}}!
Perhaps we should change this to:
* regular -> regular thread pool
* {{OOB}} -> regular thread pool
* {{INTERNAL}} -> internal thread pool
* {{OOB|INTERNAL}} -> internal thread pool

Investigate perf impact of this change

> When running UPerf in a cluster of 4, we see {{thread_pool_size_largest=39}}. Verify that MaxOneThreadPerSender works as expected: the largest thread pool size should be 4+delta (timer threads, retransmission): ~6.
> It looks as if {{MPerf}} behaves (~6 threads), but {{UPerf}} doesn't: ~26 threads
