Comment 7 for bug 2060163

Hmm, upstream CI does this:

https://github.com/openstack/devstack/blob/master/lib/neutron#L444-L448
https://github.com/openstack/devstack/blob/master/stackrc#L778-L782

If I understand this correctly, it will take the max(2, nproc/4) -- So upstream CI, we have 8 vCPUs for nodes, and based on my math that would put us at 2 workers, similar to what we do.. but it seems nothing tunes rpc_workers (however I guess that doesn't matter in an OVN situation?)

https://docs.openstack.org/neutron/latest/admin/config-wsgi.html

However, the docs do say...

> If OVN ML2 plugin is used without any additional agents, neutron requires no worker for RPC message processing. Set both rpc_workers and rpc_state_report_workers to 0, to disable RPC workers.

Which means that doesn't matter.. and upstream CI is using 2 API workers and I assume not hitting this.. I don't know. We do run in Kubernetes/containerized, so not sure if that has any impact..
