I submitted https://review.openstack.org/#/c/122013/ to set a scaling default for API_WORKERS based on the available CPUs ((nproc+1)/2). There is a summary in that commit message of the current reviews addressing the workers in various projects. I think it has become clear that DevStack needs to set a default for most services that are currently either too big (nproc) or too small (Keystone at 1). Of course, moving things to mod_wsgi moots all of that, but it'll be a while before everything moves. dt -- Dean Troyer dtro...@gmail.com
