PERFORMANCE_NOTES.txt in Advertisement 7.3

- the script tries to serve ads without using a database connection, so you'll need to set variables in settings.php only
- you need to set drupal_private_key in your settings.php

- it's either DRUPAL_BOOTSTRAP_CONFIGURATION or DRUPAL_BOOTSTRAP_PAGE_HEADER, the other phases in between take very little from DRUPAL_BOOTSTRAP_PAGE_HEADER; but the difference between DRUPAL_BOOTSTRAP_PAGE_HEADER and DRUPAL_BOOTSTRAP_FULL (in a separate, light environment) are not worth it, see below:
