<p class=MsoNormal>I have put together a simple producer (in java) that tries
to push through as much data as possible.<o:p></o:p></p>
<p class=MsoNormal>I create many threads, and each has its own connection, own direct
exchange, and own queue.<o:p></o:p></p>
<p class=MsoNormal>No matter how many connections, threads, exchanges, or queues,
‘top’ shows a single beam process at 100%, with remaining 7 cores
idle.<o:p></o:p></p>
