Increase minimum cache lifetime on high traffic sites

Drupal's core caching system allows to set minimum cache lifetimes. This means content will not be refreshed until after a certain time. For example, on busy sites, you would set the Minimum Cache Life to 1 hour. That means visitors do not see changes on your site more often than 1 hour. But it greatly helps to improve cache-efficiency and reduces your server load.

Advantages

  • Improved cache-efficiency
  • Reduced server load

Disadvantages

  • Vistors see less frequent content changes
