Lack of database cleanup routines

Problem Summary

WordPress databases accumulate clutter over time: post revisions, transient data, orphan metadata, spam comments, and expired transients. This bloat slows queries and increases backup sizes.

Performance Impact

• Slow queries: Larger tables = slower lookups
• 
  
• Increased backup size: Larger database files
• Memory usage: Database caches fill with junk
• Hosting limits: May hit storage limits

How to Detect

1. phpMyAdmin: Check table sizes
2. 
   
3. Query Monitor: Shows slow queries on bloated tables
4. Plugin audits: Check for transients left behind

Solutions

1. Limit Post Revisions

<?php
// In wp-config.phpdefine('WP_POST_REVISIONS', 3);

2. Delete Transients

DELETE FROM wp_options WHERE option_name LIKE '%_transient_%';

3>Remove Post Metadata

DELETE pm FROM wp_postmeta pmLEFT JOIN wp_posts p ON p.ID = pm.post_idWHERE p.ID IS NULL;

4>Use Cleanup Plugins

WP-Optimize, Advanced Database Cleaner.

5>Regular Maintenance

Schedule weekly or monthly cleanup.
