Many thanks indeed for calling this out. Performance is certainly a key goal for us and as part of the Quality group we've been increasing our performance test efforts over the last year and prioritising performance fixes with our dev teams. We've investigated and confirmed the controller that's looks to be the cause of this and raised an Issue here - https://gitlab.com/gitlab-org/gitlab/-/issues/214681 https://gitlab.com/gitlab-org/gitlab/-/issues/214681. Many thanks again.
