Description Brent Eagles 2015-11-09 20:51:04 UTC 
+++ This bug was initially created as a clone of Bug #1269622 +++

Description of problem:

Currently, the API and RPC worker counts are calculated to match the number of processors. Given that multiple components support multiple worker processes for different services, this can result in a lot of processes depending on the node role. Providing the ability to control the worker counts would allow purpose-driven tuning.

--- Additional comment from Brent Eagles on 2015-10-13 12:01:27 EDT ---

The relevant configuration items are found in /etc/neutron.conf and they are:

api_workers = [integer value >= 0] 
rpc_workers = [integer value >= 0]

for kilo: 0 means no separate process for worker threads
