Locally I've such values:
{
rss: 82931712,
heapTotal: 45592576,
heapUsed: 39920088,
external: 43999
}
but deployed version has such values:
{
rss: 125652992,
heapTotal: 52449280,
heapUsed: 35882816,
external: 60351
}
Locally I tested so:
1. Build app (same step before deploying).
2. Move to directory where built app.
3. Run "npm install".
4. Run "NODE_ENV=production npm start" ("node --optimize_for_size
--max_old_space_size=100 --gc_interval=100 index.js"). This command also
run "Appengine" for starting app.
Because of this memory overhead I can't use smallest instance class with
limit to 128Mb RAM. I often see in the logs:
Exceeded soft private memory limit of 128 MB with 129 MB after servicing 4
requests total. Consider setting a larger instance class in app.yaml.
After handling this request, the process that handled this request was
found to be using too much memory and was terminated. This is likely to
cause a new process to be used for the next request to your application. If
you see this message frequently, you may have a memory leak in your
application.
Why deployed version has such RAM overhead?
