How to speed up WordPress with LiteSpeed Cache

Applies to: All plans.

Before you start: You need access to your WordPress dashboard (log in at yourdomain.com/wp-admin). Your site already runs on our LiteSpeed server, so the LiteSpeed Cache plugin can talk straight to the server-level cache — no extra configuration on the hosting side is needed.

The fastest way to speed up WordPress at Maxinodes is to install the free LiteSpeed Cache plugin (often shortened to LSCache). Because every Maxinodes node runs the LiteSpeed web server, this plugin enables a built-in, server-level page cache that most other caching plugins cannot use. The result is far quicker page loads and lower resource usage, which also helps you stay inside your plan's CloudLinux limits.

Step 1: Install the LiteSpeed Cache plugin

Log in to your WordPress dashboard at yourdomain.com/wp-admin.
Go to Plugins -> Add New.
In the search box, type LiteSpeed Cache.
On the LiteSpeed Cache plugin card (by LiteSpeed Technologies), select Install Now, then Activate.

Result: A new LiteSpeed Cache menu appears in your WordPress sidebar.

Step 2: Turn the cache on

In the WordPress sidebar, open LiteSpeed Cache -> Cache.
On the Cache tab, set Enable Cache to ON.
Select Save Changes.

Result: WordPress now serves cached pages from our LiteSpeed server. The very first visit to each page builds the cache; every visit after that is served fast.

Out of the box, the plugin will not cache pages for logged-in users or sensitive pages such as the cart and checkout, so your dashboard and any store stay accurate.

Step 3: Apply our recommended starter settings

You do not need to change much. These safe defaults give most sites a big speed boost without breaking anything.

LiteSpeed Cache -> Cache: keep Enable Cache ON; leave Cache Logged-in Users and Cache Commenters OFF.
LiteSpeed Cache -> Cache -> Browser (or the section labelled Browser Cache): set Browser Cache to ON so returning visitors reuse files already on their device.
LiteSpeed Cache -> Page Optimization: turn on CSS Minify, JS Minify and HTML Minify to shrink your files.
LiteSpeed Cache -> Page Optimization -> Media: enable Lazy Load Images so images load as the visitor scrolls.

Enable one option at a time, save, then reload your site in a private/incognito window to confirm it still looks and works correctly.

Result: Your pages are cached, minified and lighter. Run your site through a speed-test tool before and after to see the difference.

Step 4: Clear the cache after you make changes

When you edit a page, switch theme or update a plugin and your change does not show, clear the cache:

Open LiteSpeed Cache in the WordPress sidebar.
Select Toolbox (or use the Purge menu).
Choose Purge All.

Result: The cache is rebuilt from your latest content on the next visit.

A note on advanced features

The plugin can also serve images through a free content-delivery and image-optimisation service from LiteSpeed (the Image Optimization and CDN -> QUIC.cloud sections). These are optional and require a free QUIC.cloud account. The four steps above are enough for a fast site — only explore these if you need more.

Troubleshooting this task

No LiteSpeed Cache menu after activating: refresh the WordPress dashboard, or deactivate and reactivate the plugin under Plugins -> Installed Plugins.
A change is not showing: clear the cache with Purge All (Step 4), then reload in a private window.
Your theme or layout looks broken after enabling optimisation: turn off CSS/JS/HTML Minify under Page Optimization one at a time to find the culprit, then save.
Site still slow with caching on: an old PHP version, a heavy plugin or a busy database can be the cause. See Why is my website slow? and How to choose the right PHP version for performance.
