    @franz1981 During my work, the first one was runNow, the second Later. (I 
would accept better names BTW)
    
    later I changed the first to later and forgot the other one :)

>                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2205
>             Project: ActiveMQ Artemis
>          Issue Type: Improvement
>          Components: AMQP
>    Affects Versions: 2.6.3
>            Reporter: clebert suconic
>            Assignee: clebert suconic
>            Priority: Major
>             Fix For: 2.7.0
>
>
> This is using Netty Executor (NIOLoop) to process AMQP.
> Instead of using a lock to enter the AMQP processing, what has issues on 
> scaling up multiple connections per queue, it's using a single threaded 
> executor.
>  
>  
> This represents a major improvement in AMQP. I will take my time to write a 
> blog post about this with multiple scenarios comparing 2.6.3, master (before 
> this change) and after. (I will post a link here to this JIRA).
