1. Optimize Database Structure

  • Delete unnecessary data: Remove drafts, deleted posts, auto-saved drafts, and spam comments. These accumulate over time and burden the database.
  • Delete post revisions: Every time you save a post revision, it creates a new record. Limit the number of revisions or disable them entirely to reduce database load.
  • Run SQL OPTIMIZE TABLE: Use the OPTIMIZE TABLE command to reclaim unused space and reduce table fragmentation.

2. Use Optimization Plugins

  • WP-Optimize: This plugin helps clean up unnecessary records, compress the database, and optimize tables.
  • WP Rocket or W3 Total Cache: Both plugins provide caching and compression features to speed up your website. WP Rocket also includes database cleanup tools for regular optimization.
  • Advanced Database Cleaner: This plugin helps manage and delete unnecessary database records.

3. Implement Caching Systems

  • Use caching: Caching reduces database load by preventing repeated queries for the same data.
  • Redis Cache or Memcached: These server-side caching solutions improve data retrieval speed in WordPress.

4. Optimize SQL Queries

  • Reduce complex queries: Simplify unnecessary or complex queries. Identify plugins or themes causing high query loads and replace them if possible.
  • Use Query Monitor plugin: This plugin monitors SQL queries on your site and identifies slow queries caused by specific plugins or themes.

5. Configure Server and PHP Settings

  • Use the latest PHP version: The latest version usually offers better performance.
  • Optimize MySQL configuration: Adjust MySQL settings to leverage caching and speed up queries.

6. Limit Database Records

  • Limit post revisions in the wp-config.php file:php
define( 'WP_POST_REVISIONS', 5 ); // Chỉ giữ lại 5 bản ghi sửa đổi
  • Disable auto-saves if not needed
define( 'AUTOSAVE_INTERVAL', 300 ); // Tăng thời gian tự động lưu lên

7. Perform Regular Cleanups

  • Schedule regular database cleanups or set up a cron job to execute SQL OPTIMIZE commands and remove unnecessary data weekly or monthly.

By following these steps, you can reduce database load and improve the overall performance of your WordPress site.
