OpenLiteSpeed for WordPress, Set Up and Tuned Properly

We install OpenLiteSpeed on your server with the virtual host, listeners and document root set up correctly for WordPress, including the rewrite rules WordPress needs for permalinks and the admin area. This is the part that trips people up, because OpenLiteSpeed does not read .htaccess the same way Apache does, and a copy-paste config usually breaks something quietly.

We configure PHP through LiteSpeed's own SAPI (lsphp) rather than a generic PHP-FPM pool, which is faster and better matched to the server. Memory limits, timeouts and process counts are set to suit your site rather than left on defaults.

If you are moving from another host as part of this, our migrate WordPress to DigitalOcean work covers the move itself, so the site lands on the new server already tuned.

LiteSpeed Cache is free and genuinely excellent, but it has a lot of settings, and the defaults are conservative. We configure it properly for full-page caching, browser caching, and cache purging so pages update when content changes rather than serving something stale.

Beyond page caching we set up the optimisation features that actually move the needle: critical CSS generation, lazy loading, image optimisation, and combining or deferring assets where it helps without breaking the layout. We test each of these rather than switching them all on and hoping, because aggressive minification is a common cause of subtle front-end bugs.

The result is a cache that is aggressive where it can be and careful where it needs to be.

Full-page caching only helps anonymous visitors on static pages. The moment someone logs in, adds to a cart, or hits a page WordPress has to build fresh, the server is back to running queries. Redis fixes the layer underneath by caching database query results, transients and sessions in memory.

We install Redis and connect it through LiteSpeed Cache's object cache integration, then confirm it is actually being used rather than silently failing back to the database, which is a surprisingly common state to find a site in. For busy admin areas and dynamic pages, this is often where the biggest server-side gains come from.

On stores this matters even more, which is why it pairs closely with our WooCommerce server optimisation work.

OpenLiteSpeed supports HTTP/3 and QUIC natively, which older stacks either cannot do or need extra proxies to bolt on. HTTP/3 reduces the round trips needed to establish a connection, and the benefit is most visible on mobile and on slower or higher-latency networks, exactly where page speed tends to hurt conversions most.

We configure the listeners and SSL correctly so HTTP/3 is actually negotiated, set up a valid certificate, and confirm it end to end rather than assuming it is on because a checkbox is ticked. Getting SSL and the listener config right is also what keeps HTTP/2 fallback clean for clients that do not speak HTTP/3 yet.

It is a genuine improvement that costs nothing extra once the server is set up to deliver it.

We measure page load and server response times before we start and again once the setup is complete, so you can see exactly what changed rather than taking our word for it. Numbers on their own are not the goal, but they make the value plain and show where any remaining bottleneck sits.

For WooCommerce we exclude the cart, checkout and account pages from full-page caching, sort out session handling so logged-in behaviour is correct, and make sure nothing is cached that should stay personal to a shopper. Caching a store wrong is worse than not caching it, so this part is done carefully.

If the site is slow for reasons the server cannot fix, such as a heavy theme or bloated plugins, we will say so, and our WordPress speed optimisation work handles that side. For ongoing peace of mind, a WordPress support retainer keeps the stack monitored and updated after launch.
