First and foremost, you may need to optimize your tables. The frequency depends on the size and usage of the database, but most databases would benefit from doing something like this on a yearly basis: a) Enter your phpMyAdmin/MySQL control panel. Click on the database (not the table, the database name), and on the right hand column your tables should be listed. Scroll down till you see the “Check all” link. Click on that link, make sure all database tables are checked and then from the dropdown next to it, and carefully select “Optimize table”.
Additionally, adding indexes to your table(s) may improve performance. If you're not sure what you're doing, it's best not to modify any table; caution is recommended. There are various articles (
http://www.whenpenguinsattack.com/2006/03/11/optimizing-mysql-tables/). It may be best to google for something like [Your Software Name] MySQL indexes" for suggestions.
Wordpress Users: (
http://wordpress.org/): It is important to keep up to date with this software; vulnerabilities have been found in past versions. Regardless, installing the "Wordpress Cache" plugin can greatly reduce resource usage and improve performance (
http://wordpress.org/extend/plugins/wp-cache/). If you're not using the current version of Wordpress, keep in mind that v2.1+ is much faster than older versions.
Mambo Users: (
http://www.mamboserver.com/): As of May 2007, the current version is 4.6.2. Older versions likely have security issues. It is important to update to the current version (
http://mamboxchange.com/frs/?group_id=5), especially since Mambo/Joomla is an extremely popular exploit target due to the widespread use of this software.
Joomla Users: (
http://www.joomla.org/) As of May 2007, the current version is 1.0.12. Older versions have critical security issues, and must be upgraded to the current version (
http://dev.joomla.org/content/blogcategory/21/86/). Mambo/Joomla is an extremely popular exploit target due to the widespread use of this software. You may want to look at a plugin that optimizes the tables (
http://forum.joomla.org/index.php?topic=160051.msg771662).
osCommerce: (
