      {create:always}

      ' --report-total --report-header=no --timestamp=yes --sequence=no --durable False --connection-options '

      {tcp-nodelay:true,reconnect:true,heartbeat:1}

      ' --messages 0 --content-size 120240000 --send-rate 1
      qpid-receive -b 'amqp:rdma:192.168.1.1' -a 'benchmark-0;

      {create:always}
