> I build QPID 0.32 C++ broker with HA module on CentOS6.5 and run a cluster of 2 nodes
with --ha-replicate=all, Then send messages using QPID Messaging API continuously with protocol
AMQP0-10 and I meet a strange problem,If I purge all of messages in a queue and continue to
send messages,The throughput drop sharply. And the same problem seen on QPID 0.34
> Steps to reproduce:
> 1:
>     qpid-config add exchange direct testHA.exchange
>     qpid-config add queue testHA.queue --max-queue-size 1048576000
>     qpid-config bind testHA.exchange testHA.queue testHA.binding
> 2:
>     Run "qpid-queue-stats -f testHA.queue" on a console
> 3:
>     Send 100000 messages to testHA.exchange with routingkey testHA.binding
> 4:
>     Purge queue use the QPID manager tool (qpid-tool)
> 5:
>     Repeat step 3
> get the output from step 2:
> Queue Name          Sec        Depth    Enq Rate    Deq Rate
