Hi,
As per the Release Notes <https://cloud.google.com/release-notes>, there is no update recently on App Engine Standard auto-scaling scheduler. In the app.yaml files you provided, I could see a huge difference for ‘min_pending_latency’. Are you aware of it? If it is expected, I would suggest sampling typical periods of time between the different patterns and closely inspecting and cross checking on any possible traffic difference. Hope it helps!
