node.js - why does google appengine deployment take several minutes to update service

Question

I'm using nodejs flexible environment documented here

Nothing fancy in the config

runtime: nodejs
vm: true
service: SimpleExpressService
health_check:
  enable_health_check: False
automatic_scaling:
  min_num_instances: 1
  max_num_instances: 4
  cool_down_period_sec: 120
  cpu_utilization:
    target_utilization: 0.5

Here is my deployment command

gcloud app deploy -q --promote --version $VER

Whenever I deploy a new version, almost everything goes really fast. However, the step 'Updating service [SimpleExpressServer]' takes several minutes.

Is there anyway to optimize this step?
