[jboss-jira] [JBoss JIRA] (JGRP-2478) Fibers: test performance versus regular threads

[Bela Ban (Jira)]

     [ https://issues.redhat.com/browse/JGRP-2478?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bela Ban updated JGRP-2478:
---------------------------
    Fix Version/s: 5.0.0.Final
                       (was: 5.1)


I made all dependencies on fibers and JDK 16 stuff dependent on the presence of fibers (using {{MethodHandle}}), so this stuff can still go into 5 final as it compiles and doesn't hamper 5.

> Test performance on the latest JDK-15-loom with {{use_fibers="true"/"false"}}.
> This requires a few code changes:
>  * There's no need to pool fibers, see [1] for details
>  * If fibers are used, {{thread_pool}} and {{internal_pool}} in {{TP}} could be assigned the result of {{Executors.newVirtualThreadExecutor()}}
>  * In a future version, we could simply remove the 2 thread pools
