This is a debian wheezy box. I installed erlang from the debian repo, i.e. apt-get install erlang I think. Erlang is R15B01. We do have a number of rabbitmq installs on various boxes and different versions of erlang, etc. I have tried this at least three different boxes with similar results. On a beefy VM on new fast hardware I see about 23-25kHz compared to the 15kHz I reported to you. In all cases everything is running local, no lan network issues to consider. We generally run debian or ubuntu installs with very little if any changes. In all my testing this morning using your example command I never see anything close to what you reported. 25kHz is the absolute max I see on that shinny new VM.

The output from rabbitmqctl status is

Status of node 'rabbit at geib-2950' ...
     [{rabbitmq_management,"RabbitMQ Management Console","3.1.3"},
      {rabbitmq_management_agent,"RabbitMQ Management Agent","3.1.3"},
