6.15.1.2.2. RabbitMQ performance (Client -> Slave-1, Server -> Slave-2)

This report contains results of Message Queue Performance execution with Oslo.messaging Simulator. Simulator client and simulator server are connected to different slave nodes. RabbitMQ HA queues are enabled.

Simulator is configured with eventlet executor running in 10 threads. The overall number of threads is calculated as multiplication of eventlet threads, number of processes and number of used nodes.

6.15.1.2.2.1. Test Case 1: RPC CALL Throughput Test

6.15.1.2.2.1.1. Message processing

Messages are collected at 3 points: sent - messages sent by the client, received - messages received by the server, round-trip - replies received by the client. Also the number of lost messages is calculated. Sizes of messages is based on the distribution of messages collected on the 100-node cloud.
