The RPC call rate goes from 35 RPC calls/sec to 812 RPC calls/sec. The blueprint can be found here: https://blueprints.launchpad.net/oslo/+spec/amqp-rpc-fast-reply-queue The code review here: https://review.openstack.org/#/c/19721/ For those interested, please review the code so that it can be approved.
