Pipelines page for gitlab-org/gitlab-ce times out
The page https://gitlab.com/gitlab-org/gitlab-ce/pipelines times out, despite recent improvements to this controller (https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/18427 for example). Looking at Grafana I don't see anything that suggests this is affecting everybody: https://performance.gitlab.net/dashboard/db/rails-controllers?orgId=1&var-action=Projects::PipelinesController%23index&var-database=Production&from=now-24h&to=now
