Drupal Configuration: Boosting performance by Caching

Drupal Configuration Step By Step Tutorial - Part 6: To boost performance our site, we can use cache system. Cache can speed up a site significantly. We don't need always retrieve content of page from database. Especially, that page never changing (change only once).

To set cache, you can access Administer > Site Configuration > Performance.

Although cache can speed up site, cached page servers an old version of page. Thus, user can see most recent one. It become problem when our site is active site and always add/change post in short time. For this problem, we can set minimum chache lifetime. This setting determines how long Drupal holds a page in its cache.
