For those not having enough time to go over the Dell presentation at the
above link, the short summary is the amqp-rpc-fast-reply-queue blueprint
provides a 23 times improvement to RPC call over a cluster of three
RabbitMQ servers with mirroring enabled.  The RPC call rate goes from 35
RPC calls/sec to 812 RPC calls/sec.

The blueprint can be found here:

For those interested, please review the code so that it can be approved.
