We're running on Flexible. Here is my app.yaml:

service: ranking
runtime: python
runtime_config:
    python_version: 2
vm: true
entrypoint: gunicorn -b :$PORT main:app

resources:
  cpu: 32
  memory_gb: 120

manual_scaling:
  instances: 3

We're testing various configurations of gunicorn like

gunicorn -b :$PORT --threads=64 main:app.

Until now we could get QPS around 28 with CPU utilization 70% and we're
trying to push more.
I'm just wondering if there is any hard limit on in-flight requests.
