Hi Mohammed,
    The max number of conns for RabbitMQ is estimated through cacluating the 
conns of nova and cinder components. We have 3000 compute nodes, 3 control 
nodes and 15 cinder-volume nodes, We deploy rabbitmq on control nodes and use 
master-slave mode, the totally conns of RabbitMQ is almost 2w, so we set 2w 
for RabbitMQ configuration.
    Before deploying the SB relay, each ovn SB process needed to manage an 
average of 600+connections, the CPU usage is often 100% and the requests is 
slow processing. After adding the relay, each relay process handles about 60 
connections, the total relay process is set to 10. After testing, each relay 
process has a low CPU usage and can process information quickly.

Hi Alex,

Thanks for the great write up!  I would love to see more of this.

How did you adjust the max number of conns for RabbitMQ and for the relay I
assume you used https://docs.ovn.org/en/latest/tutorials/ovn-ovsdb-relay.html
<https://docs.ovn.org/en/latest/tutorials/ovn-ovsdb-relay.html> ?

Thanks

Mohammed
