Hi Aleksander, 

We agree without doubt that in an ideal world reaching perfection is a 
realist target. Even in our real world, I am sure Developers would like to 
fine-tune all products to perfection, but in a real world time is an issue. 
There are serious issues to address and to fix, whose urgency has to be met 
with timely results. As a consequence, in your particular case, if you 
indicate solution works and is enough for you, it should come as no 
surprise that Engineering would rather concentrate on outages and urgent 
fixes to be implemented right now. Your understanding is much appreciated. 

There is an unexpected result of your optimizations: how much did your 
changes contribute to improvement, vs. the Engineering solution; difficult 
to judge.

Hi George.
For me it's enough now, but exists such saying: there is no limit to perfection 
-:).
I also made some optimizations therefore now I'm able to use most small 
instance.
But if exists opportunity to improve that, of course would be still better.

If you will know own documentation better you will understand me. But ok, I 
will explain to you.

if to follow on the link:
https://cloud.google.com/appengine/docs/standard/nodejs/building-app/deploying-web-service

there is phrase:
"Node.js modules are installed in the cloud as listed in your package.json
 and package-lock.json files and your service is started by using npm start.
"

That's if we will define "scripts" / "start" section in "package.json" then 
my service will started by this command.

I use such command to decrease use RAM and because my script called 
"index.js" instead of "server.js":
"scripts": {
 "start": "node --optimize_for_size --gc_interval=100 index.js"
}

But you didn't understand essence of the issue.

Ok, special for testing I created "hello-world" example without "scripts" 
section in "package.json" and only added to first line in "index.js" next 
command: "console.log(process.memoryUsage());".

When I execute it locally by next command "NODE_ENV=production npm start" I 
see in the console a following results:
{ rss: 20860928,
  heapTotal: 7159808,
  heapUsed: 4417056,
  external: 8224 }

But when it's deployed it logs a following results:

{ rss: 55054336, 
  heapTotal: 7159808, 
  heapUsed: 4258536, 
  external: 8224 }

What is it meant here by: "This command also run "Appengine" for starting 
app."? How did you deploy your app? The usual command is gcloud app deploy. 
You may find more related information in the "Quickstart for Node.js in the 
App Engine Standard Environment" online document. [1]

What is the structure of your app? One would expect: 

my-nodejs-service/
  app.yaml
  package.json
  server.js

More related information may be read on the "Writing Your Web Service with 
Node.js". [2]

It seems you run your app locally with parameters that differ by reference 
to the deployed app. 

What is the output of the "gcloud info" command in your local environment?

[google-appengine] Re: Node.js Standard: memory usage different for locally and deployed version on 30 - 40 Mb.

[mr . efrem]

I use "MacOs", but "App Engine" uses "Linux". Maybe therefore is such 
different? "Node.js" version "v8.11.2" is same as on "App Engine".
