Updating/installing any module takes a lot of time

Hello there!
lately I can't updating/installing any module takes a lot of time; here a few info:

28 Oct 23:20:45 - [info] Node-RED version: v2.1.3
28 Oct 23:20:45 - [info] Node.js  version: v14.18.1
28 Oct 23:20:45 - [info] Linux 5.10.0-9-amd64 x64 LE

My instance run on Docker on a Debian 11 machine, here my docker-compose file:

  node-red:
    container_name: nuc_nodered
    ports:
      - "1881:1880"
    volumes:
      - ./docker/nodered:/data
      - /etc/localtime:/etc/localtime:ro
    image: nodered/node-red:latest
    restart: unless-stopped
    environment:
      - TZ=Europe/Rome

I've activated trace level log, when I update a module with the palette this is the log output

28 Oct 23:32:53 - [trace] npm["install","--no-audit","--no-update-notifier","--no-fund","--save","--save-prefix=~","--production","--engine-strict","node-red-contrib-deconz@2.0.8"]

Five minutes for a single package: is it normal?
With previous version of NR it was much faster.

EDIT:
Now all my modules update fails after a random number of minutes with ETIMEDOUT errors, like the following

Miscellaneous Warning ETIMEDOUT: request to https://registry.npmjs.org/lodash.random failed, reason: connect ETIMEDOUT
I tried a wget https://registry.npmjs.org/lodash.random and it randomly work.

Thanks!

What hardware are you running on?

Do you have a good internet connection of reasonable speed?

Are you running in a home environment or corporate, possibly with firewalls and so on?
