Bug Description

The number of workers processing Neutron jobs is currently not configurable. It should be, and have a default to scale relative to the number of cores on the machine.

Nova CC change merged; however needs adding to the neutron-api service as well.

Can we also have a good relative value for rpc_workers in neutron.conf as well as api_workers?

As far as I understand, neutron-server launches just one rpc worker at this moment.

For icehouse, I know the rpc_workers feature was experimental - we'll look and see if that's sensible for Juno.

Thanks for the feedback!

Fair enough. My motivation was to ease the known issue below. Without increasing rpc_workers, one neutron-server process tends to occupy one CPU core all the time.
