This module is discontinued at the moment.
I am not maintaining any Drupal 5 sites at the moment, so it is very unlikely to have any updates of this module. As to Drupal 6 there are better way of optimizing database problem. If someone wants to take over, please let me know.
Allows users (everyone, including admin) to cache queries for a certain time. It works perfectly with tables like 'system', 'variables', etc. These tables hardly ever change during the standard application life.
Used on high traffic pages (5 million pages per month, 40000 users). Works perfectly well.
This module is useful if you fight with overloaded database server.
