Doc Type: Enhancement
Doc Text:
This update adds a new option for the Block Storage API service, namely osapi_volume_workers. This option allows you to specify the number of API service workers (or OS processes) to launch for openstack-cinder-api. Typically, this option can be used to set the number of OS processes to the number of CPU cores/threads on a machine; doing so will greatly increase the number of API requests that can be handled per second. To set this option, run the following command on the openstack-cinder-api host: openstack-config --set /etc/cinder/cinder.conf \ DEFAULT osapi_volume_workers [X] Replace [X] with the target number of OS processes you wish to set. By default, the Block Storage API service will still run in one process (that is, osapi_volume_workers is set to None).

Description RHOS Integration 2013-12-12 16:39:45 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/cinder/+spec/multi-process-api-service.

Description:

Due to the limit of Python interpreter, API service of Cinder can't really utilize underlying multi-core architecture even libraries like eventlet has been used.  To make API service much more scalable, we should adopt multi-process API workers mode that has been used for long time in Glance/Swift/Nova.
