App Engine Flex high latency and delay in start instances

I have a problem with the start of new instances. My system has a large flow, where it goes down and up quickly. As the flow rises fast, the survey of instances is unable to keep up, thus causing the slowness. After a while it stabilizes, but until then it causes high latency. Can anyone help?

My app.yaml:

runtime: nodejs
env: flex
automatic_scaling:
  min_num_instances: 2
  max_num_instances: 12
  cool_down_period_sec: 120
  cpu_utilization:
    target_utilization: 0.2
resources:
  cpu: 2
  memory_gb: 8

Through the app engine panel, my average CPU usage is 20% and 8Gb memory. I don't understand why it is slow if the machine doesn't work to the limit. Thanks!
