Speeding up WordPress
Practical measures: caching, image optimization, PHP version and removing unneeded plugins.
The servers run on LiteSpeed, so the biggest gain often comes from caching and tidy site content. For a general overview of causes of slowness see Slow website.
- Measure first. Test the site with a tool such as PageSpeed Insights or GTmetrix and note the results before any changes.
- Enable caching. Install the LiteSpeed Cache plugin from the WordPress admin (Plugins → Add New) and enable basic page caching (LiteSpeed Cache → Cache). Availability depends on your plan.
- Optimize images. Before uploading, reduce image dimensions and file size and use the WebP format. LiteSpeed Cache also offers image optimization.
- Use a newer PHP version. Newer 8.x versions are faster: Changing the PHP version.
- Remove the unnecessary. Delete unused plugins and themes and rarely needed features.
- Update WordPress, themes and plugins: Updating WordPress.
Database#
Occasionally delete old post revisions, spam comments and expired temporary data (transients). In phpMyAdmin you can run Optimize table on larger tables.
If the site is still slow#
Look at cPanel Metrics → Errors and Visitors to see whether you have unusual traffic or errors. Then send us a ticket with the site address and a description of when the slowdown happens.
