Also, as Valentin mentioned. Performance of any application, not just
NGINX, that logs a lot of data is going to be terrible when you actually
manage to do this.

There are many flaws in the The Factor-Factor App document and whilst it
may work out for you backend services I wouldn't recommend following it
too closely for any core infrastructure.
