[jira] [Updated] (ARTEMIS-1307) Improve performance of OrderedExecutor

["Francesco Nigro (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ARTEMIS-1307?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Francesco Nigro updated ARTEMIS-1307:
-------------------------------------
    Description: 
The current ordered executor is using ConcurrentLinkedQueue that:
- has expensive queue::size operation (ie O( n ))
- has node instances scattered in the heap  

There are faster and cheaper alternatives in specialized libraries (eg JCtools) that could be used instead of it to be more friendly with the GC and to provide more throughput too when CPU bound.
