Is mass upgrade a parallel process? #211

Dear friends, does mass firmware upgrade process happen in parallel for many devices?

Potentially yes, it depends on how the server is configured, see openwisp2_celery_firmware_upgrader_concurrency and openwisp2_celery_firmware_upgrader_autoscale in https://github.com/openwisp/ansible-openwisp2. See also https://docs.celeryq.dev/en/stable/userguide/workers.html (look for concurrency and autoscaling, they are two different ways to increase concurrency, one is fixed and the other is dynamic).
