[rabbitmq-discuss] rabbitmq cluster with all but one node shutdown

Hi,

With RabbitMQ version 2.8.7 on erlang R15B02 setup as a cluster of 3
machines.  Each queue is setup to mirror and durable.  Each node is a disc
node.  Server 1 is the master and stats during the tests.

I am wondering if the following is expected.
I have a single client communicating to another client both connecting
through Server 1.   If I shut down servers 2  and 3 in my cluster and run my
application again the performance is 47 times slower than when I have all 3
servers running.  Is this expected?  I do not have load balance between my
clients and the rabbit cluster.

I honestly was expecting the single node to actually perform a little better
as it would not have to replicate data to the other two nodes.

-Mark
