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.
