How to Clean and Optimize Your WordPress Database for Instant Queries
Over months of editing, WordPress accumulates thousands of obsolete post revisions, auto-drafts, orphaned post meta, and expired transient records.
1. Limit Post Revisions in wp-config.php
By default, WordPress stores infinite revisions of every blog post. Add define('WP_POST_REVISIONS', 5); to keep your database lean.
2. Purge Orphaned Meta and Expired Transients
Use SQL queries or lightweight optimization plugins to clean out residual plugin settings left behind by uninstalled extensions.
