My Ubuntu server runs several applications built in Python (Django or Flask), and deployed using gunicorn. Some of them also use nginx. I would like to give some of these applications a higher priority, so that, if a prioritized application is used, its performance will not be hurt by non-prioritized applications used at the same time.
I know the Unix command nice could be used for giving different priorities to processes, but I do not know where exactly to apply this command: to the Python app? to the gunicorn command line? to nginx?
