WordPress Website Optimization

Optimizing your WordPress website

There are several ways to optimize your WordPress website for faster loading and better handling of simultaneous visitors. Below are a number of easy-to-implement tips:

• Use a recent PHP version:

PHP 7 is much faster than PHP 5, and PHP 8 is even faster than PHP 7. Always use the second most recent PHP version.

More info: Changing PHP version (Web- and Reseller Hosting) or Changing PHP version (WordPress Hosting).

• Optimize your PHP settings:

Recommended settings:

• max_input_vars: 5000
• memory_limit: 512M
• post_max_size: 128M
• upload_max_filesize: 128M

Also ensure the redis and opcache extensions are enabled.

• Use (server-side) caching:

Install LiteSpeed Cache if supported, otherwise use W3 Total Cache.

• Limit the number of plugins:

Ideally, use no more than 25 plugins. Remove unused plugins and select well-maintained ones.

• Optimize your database:

Clean up old data and regularly optimize the database.

• Keep WordPress, themes, and plugins updated:

Regular updates not only enhance security but also improve performance.

• Check log files for errors:

Errors can significantly slow down your site. Check and resolve them.

• Disable WP_CRON:

Configure WP_CRON as a real cronjob to reduce server load.

More info: Disabling WP_CRON for better performance.

• Choose a lightweight and well-maintained theme:

Paid themes (e.g., via ThemeForest) often offer better support and performance.
