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!
