Saving cache too slow for npm / node projects (node_modules directory)

Summary

When using cache with npm / projecs caching the node_modules directory takes 12 minutes

Steps to reproduce

my yaml file (extract as example)

test-compile-development:
  image: node:12.14.1
  stage: test-compile

  cache:
    paths:
      - node_modules/

  before_script:
    - npm install

  script:
    - npm test -- --reporters=jest-junit
    - npm run build

  artifacts:
    reports:
      junit: junit.xml
    paths:
      - dist/

What is the current bug behavior?

Saving the cache takes a lot of time... in my case >10minutes

What is the expected correct behavior?

It should be fast as in other projects using cache
