  • How does Drupal find the correct code to execute?
  • Which parts of the page come from the cache and which ones are built from scratch? Which queries are executed against the database?
  • And, why not, how many time and memory the request requires to be converted in a response?

Whether if you are a contrib developer or a simple curious person the answers to those questions will let you better understand how Drupal 8 works.
