A slow WordPress site affects both visitor experience and how comfortably it handles traffic. The good news is that most speed problems come down to a short list of common culprits. Work through this checklist to find the easy wins.
1. Turn on caching
Caching is usually the single biggest speed improvement available. Rather than rebuilding a page from scratch on every visit, a cached copy is served directly, cutting out repeated database and PHP work. If your hosting includes server-level caching, such as LiteSpeed’s LSCache, make sure it’s enabled and configured for your site through the LSCache plugin rather than relying on a generic caching plugin alone, since server-level caching typically outperforms a plugin-only approach.
2. Optimise your images
Large, unoptimised images are one of the most common causes of slow page loads. Before uploading:
- Resize images to the actual dimensions they’ll display at, rather than uploading full camera or design-tool resolution.
- Use a modern, compressed format where possible.
- Consider an image optimisation plugin that compresses images automatically on upload.
- Enable lazy loading so images below the fold don’t load until a visitor scrolls to them.
3. Audit your plugins
Every active plugin adds some amount of processing to each page load. Periodically review your installed plugins and:
- Remove any that are inactive or no longer needed.
- Watch for plugins that duplicate functionality (two SEO plugins, two caching plugins) and keep only one.
- Be cautious with plugins that run heavy processes on every page load, such as some page builders or all-in-one “everything” plugins.
4. Keep your PHP version current
Running a current, supported version of PHP can make a noticeable difference to how quickly your site executes code, since newer PHP versions are generally faster than older ones. Check your PHP version in cPanel under MultiPHP Manager and update it if you’re on an old version, testing your site afterwards to confirm your theme and plugins are compatible.
5. Choose a lightweight theme
Heavier, feature-packed themes with built-in page builders and animation libraries can add overhead that a simpler theme avoids. If your theme feels sluggish even with caching and image optimisation in place, it’s worth testing a lighter-weight alternative to see how much of a difference it makes.
6. Consider a CDN for global visitors
If a meaningful share of your traffic comes from outside Australia, a content delivery network (CDN) can help by serving static assets like images, CSS and JavaScript from locations closer to those visitors. For a primarily Australian audience, hosting location typically matters more than a CDN, since your visitors are already close to the server.
7. Host close to your audience
Where your server is physically located affects how far data has to travel to reach your visitors. If most of your audience is in Australia, hosting on a server in an Australian data centre reduces that distance. Skyrack’s hosting servers are located in a Sydney data centre, with DNS nodes across Australia, so Australian visitors are served from nearby infrastructure rather than overseas.
8. Re-test after each change
Speed optimisation works best as an iterative process. Make one change at a time, then re-test your site’s load time so you can see what actually made a difference, rather than changing several things at once and guessing which one helped.
