Performance

This solves a unique issue with a multisite setup and the CDN module.

Optimize SQL queries or views by using index tables which (partially) shadows the original query output.

UPDATE: Looking at Cache Backport, this module seems somewhat ridiculous ... I have now abandoned it.

Cache Heuristic keeps track of which cache-entries are loaded a page, and bundles the cache loads by taking advantage of Cache->getMultiple(). Resulting in a reduced number of queries to the caching backend.

To enable, add to settings.php:

Drupal 6

NOTE: Requires Cache Backport

<?php
$conf['cache_backends'] = array(
  'sites/all/modules/cache_heuristic/cache_heuristic.inc'
);

$conf['cache_inc'] = 'sites/all/modules/cache_backport/cache.inc';
$conf['cache_default_class'] = 'HeuristicCache';
$conf['heuristic_cache_default_class'] = 'DrupalDatabaseCache';
?>

Drupal 7

<?php
$conf['cache_backends'] = array(
  'sites/all/modules/cache_heuristic/cache_heuristic.inc'
);

$conf['cache_default_class'] = 'HeuristicCache';
$conf['heuristic_cache_default_class'] = 'DrupalDatabaseCache';

// Example: Use memcach for the menu cache
$conf['heuristic_cache_class_cache_menu'] = 'MemCacheDrupal';
?>

Graceful caching

You can mix and match caching backends, e.g. adding graceful caching to the Drupal 7 example above using Cache Graceful


<?php
$conf['cache_backends'] = array(
'sites/all/modules/cache_graceful/cache_graceful.inc',
'sites/all/modules/cache_heuristic/cache_heuristic.inc',
);
