After installing Openstack IceHouse, I performed some benchmarks to find the Volume Performance was fairly slow (9 Mb/s, as opposed to 80 Mb/s on the host machine). To correct this, I attempted to switch the message queuing system to ZeroMQ, which boasts much faster performance in general to the default RabbitMQ. However, there is very little documentation, and I am asking for help here.

The setup is composed of 4 machines, the controller, network, compute1, and block1 hosts. I am editing the nova.conf on the controller and compute1, cinder.conf on block1, and neutron.conf on network, setting...

rpc_backend = zmq
rpc_zmq_host = <host>
rpc_zmq_matchmaker = oslo.messaging._drivers.matchmaker_rung.MatchMakerRing
rpc_zmq_bind_address = *
rpc_zmq_ipc_dir/var/run/<openstack, cinder, or neutron>

In addition, I am manually starting the zmq receiver...

compute1:/$ oslo-messaging-zmq-receiver --config-file /etc/nova/nova.conf
block1:/$ oslo-messaging-zmq-receiver --config-file /etc/cinder/cinder.conf
network:/$ oslo-messaging-zmq-receiver --config-file /etc/neutron/neutron.conf
controller:/$ oslo-messaging-zmq-receiver --config-file /etc/nova/nova.conf

Currently, it is not working. In the controller's ipc directory, I see a single open socket. In others, the logfiles show failed connections - Timeout while waiting on RPC response - topic: "<unknown>", RPC method: "<unknown>", info: "<unknown>",.

Any aid about zeroMQ setup would be appreciated.
