Based on reading some logs, it looks like requirements updates are getting regenerated on every requirements land for all open patches, even if they aren't impacted by it - https://review.openstack.org/#/c/351991/ patch 10,11,12 in that series are just rebases, all happening within a couple of hours. With the check queue at ... 505 changes as of this email, this is definitely adding some extra load to the system. It would be a great optimization for someone to look at the script - https://github.com/openstack-infra/project-config/blob/ab89ab40ed74db306ce10e36341d39f23231f012/jenkins/scripts/propose_update.sh and make it so that if the commit did not change, don't push a rebased review. -Sean -- Sean Dague http://dague.net
