Recommended Celery Django settings for reliability. For more details, check the DjangoCon 2023 talk "Mixing reliability with Celery for delicious async tasks" by Flávio Juvenal: https://youtu.be/VuONiF99Oqc
# Recommended Celery Django settings for reliability:
# (use `app.config_from_object('django.conf:settings', namespace='CELERY')`
# in proj/celery.py module)
from decouple import config # use python-decouple: https://github.com/HBNetwork/python-decouple
# Prefer RabbitMQ over Redis for Broker,
# mainly because RabbitMQ doesn't need visibility timeout. See:

GCC compiler optimization for ARM-based systems

GCC compiler optimization for ARM-based systems

2017-03-03 fm4dd

The gcc compiler can optimize code by taking advantage of CPU specific features. Especially for ARM CPU's, this can have impact on application performance. ARM CPU's, even under the same architecture, could be implemented with different versions of floating point units (FPU). Utilizing full FPU potential improves performance of heavier operating systems such as full Linux distributions.

-mcpu, -march: Defining the CPU type and architecture

These flags can both be used to set the CPU type. Setting one or the other is sufficient.
