In our third-party CI (IBM KVM on Power) we run both stable/mitaka and master on Ubuntu Xenial. I went ahead and plotted dstat graphs, see http://dal05.objectstorage.softlayer.net/v1/AUTH_3d8e6ecb-f597-448c-8ec2-164e9f710dd6/pkvmci/dstat20170202/ . It does look like there is some difference in overall memory use - mitaka uses a bit less. This is anecdotal, but still is an extra data point. Also note that we have 12G of ram, and we do not see oom kills. > I agree it's more likely bloat in some > commonly-used module (possibly even one developed outside our > community), but potential system-level overhead probably should also > get some investigation. > -- > Jeremy Stanley > > __________________________________________________________________________ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev Mikhail Medvedev IBM __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
