Does Drupal parse (and/or run) hooks that are unrelated to the content being loaded by the current user?
For example, say I had a module foo installed and active with the following hooks:
<?php // .. stuff ... function foo_menu() { $items = array(); $items['foo/show'] = array('title' => t('Foo!'),'page callback' => 'foo_display_all','description' => 'All our foo are belong to you','type' => MENU_NORMAL_ITEM, ); return $items; } function foo_display_all() { // About 100 lines of code }// ... stuff ...Would Drupal parse (and thus effect the load time) for pages that aren't listed in foo_menu? Put another way, would the length and complexity of foo_display_all effect how www.example.com/bar loads?
At risk of having two different questions here, I'll say I would be grateful for an explanation (or link to an explanation) of how and why Drupal does or does not parse, rather than a yes/no answer.
