6.15.1.2.1. RabbitMQ performance (Client and Server connected to Master)

This report contains results of Message Queue Performance execution with Oslo.messaging Simulator. Both simulator client and simulator server are connected to Master node. RabbitMQ HA queues are disabled.

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.

6.15.1.2.1.1. Test Case 1: RPC CALL Throughput Test

6.15.1.2.1.1.1. 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.

RPC CALL Message count

threads	sent, msg	received, msg	round-trip, msg	lost, msg
50	301010	301010	301010	0
