1) Should we explicitly set the number of workers that services use in devstack? Why have so many workers in a small all-in-one environment? What is the right balance here?
There is a review out for that [1]. Devstack has a switch for everything, and this one seems more susceptible to bit-rot than others. It could be achieved with local.conf values appropriate to each environment. My preference is something like that, but I'm also happy to be out-voted
2) Should we be worried that some OpenStack services such as nova-api, nova-conductor and cinder-api take up so much memory? Does there memory usage keep growing over time, does anyone have any numbers to answer this? Why do these processes take up so much memory?
I'm not aware of anything explicitly tracking this. It might be interesting to have certain jobs query rss sizes for processes and report them into graphite [2]. We could even have a devstack flag :) -i [1] https://review.openstack.org/#/c/117517/ [2] http://graphite.openstack.org/ _______________________________________________ OpenStack-dev mailing list OpenStack-dev@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
