Most hosting companies run Apache because that’s what they’ve always run. We run LiteSpeed. Here’s what that actually changes for your website, in terms that have nothing to do with server jargon.
Every website sits on a web server, the software that receives a visitor’s request and sends back the page. It’s invisible, nobody shops for it, and for twenty-odd years the default answer has been Apache.
We use LiteSpeed instead. It’s a paid, commercial server rather than the free default, and the difference shows up in the two things a business actually cares about: how fast the site feels, and whether it stays standing when traffic arrives.
The Difference Is How It Handles Visitors
Apache’s traditional model assigns a separate process to each connection. It works, but every process consumes memory whether it’s doing anything useful or not, so a burst of visitors means a burst of memory use.
LiteSpeed uses an event-driven architecture instead, fewer processes handling many connections at once. In LiteSpeed’s own words, it can “securely handle thousands of concurrent clients while consuming minimal memory and CPU,” which they contrast directly with Apache’s process-based model as “fewer processes, less overhead, and enormous scalability.”
It matters most on your best day, not your average one. When a post does well, an ad runs, or you get mentioned somewhere, the traffic that would slow a conventional setup to a crawl is the traffic LiteSpeed is designed to absorb.
Caching That Lives in the Server, and the Plugin That Drives It
Caching means keeping a ready-made copy of a page so the server can hand it straight over instead of rebuilding it from the database every time someone visits.
Most WordPress caching plugins do that work themselves, inside WordPress, which means PHP has already started running before the cache helps. LiteSpeed’s cache, LSCache, lives in the web server itself. LiteSpeed’s own documentation puts the difference bluntly: “LSCache is a server-level cache, so it’s faster than PHP-level caches.” They describe it as an “advanced server-level cache with hole-punching through ESI” that removes the need for “an HTTPS reverse proxy or additional 3rd party caching layers.” Hole-punching is the clever part: a page can be cached while small dynamic pieces of it (a shopping cart, a logged-in user’s name) stay live.
The LiteSpeed Cache plugin is not optional: it’s the steering wheel
This is the part that’s easy to get wrong, so let’s be precise about it: the LiteSpeed Cache plugin matters, and every one of our WordPress sites runs it.
The server has the cache engine. The plugin is how WordPress tells that engine what to do. Without it, the cache would be driven by hand-written rewrite rules in .htaccess. LiteSpeed’s documentation describes the plugin’s job exactly this way, “An LSCache plugin bridges the knowledge gap between a web app and the Cache Engine”, and “LSCache plugins are a way of communicating these web app rules to the Cache Engine.”
In practice that means WordPress-aware caching: which pages can be cached, for how long, and, critically, which events should purge them. Publish a post, take a product out of stock, or approve a comment, and the right pages clear themselves. That intelligence has to come from inside WordPress, because only WordPress knows those things happened.
Everything is tunable per site, from the WordPress dashboard: no server configuration, no support ticket, no risk to anyone else’s site. A single site’s caching can be adjusted without touching the server at all.
The plugin is also free and open source. LiteSpeed states “LSCWP will always be free and open source”, and it does considerably more than page caching. It handles image optimisation with WebP and AVIF support, CSS, JavaScript and HTML minification, lazy loading of images and iframes, and database cleanup. Those optimisation features work on any server; the server-level page cache is the part that needs LiteSpeed underneath it.
So it isn’t server versus plugin. It’s a fast cache engine in the server, driven by a free plugin that understands WordPress. You need both halves.
Security and Modern Protocols
LiteSpeed processes “popular ModSecurity rulesets with maximum efficiency”, the same web application firewall rules the industry already uses, and it does so alongside “a host of built-in anti-DDoS features, such as bandwidth and connection throttling.”
It’s also ahead on HTTP/3, the current generation of the protocol browsers use to talk to websites. LiteSpeed states it was “the first to provide a production-ready implementation” of it. For a visitor on a phone with patchy signal, HTTP/3 is the difference between a page that loads and a page that stalls.
Nothing Has to Be Rebuilt to Use It
A fair question about any non-default technology is what it breaks. In this case, nothing. LiteSpeed is designed as “a drop-in replacement for an Apache web server”, it reads Apache configuration files directly, supports .htaccess, and “can be used with any control panel that was designed for Apache.”
Your WordPress site doesn’t know or care which server it’s on. It just gets served faster.
Page speed affects two things that cost real money: how many visitors stay long enough to read anything, and how Google assesses the page. A slow site loses people before they ever see what you do.

Frequently Asked Questions
Do I need to change anything about my website to use LiteSpeed?+
No. LiteSpeed is a drop-in replacement for Apache, it reads the same configuration files and supports.htaccess, so a standard WordPress site works exactly as it did before. We handle the migration, and there’s nothing for you to reconfigure.
Is this the same as a caching plugin?+
It’s both, working together, and that’s the point. A conventional caching plugin does the caching itself inside WordPress, so PHP has already started running before the cache helps. With LiteSpeed the cache engine lives in the server, and the free LiteSpeed Cache plugin is what tells that engine the WordPress-specific rules: what to cache, for how long, and what should purge it when you publish or update something. You want both. The plugin isn’t a lesser substitute for the server cache, it’s how you drive it, from your own dashboard, without touching server settings.
Will my site definitely be faster?+
The server is one of several factors, a heavy theme, oversized images, or too many plugins will slow a site down on any hosting. What LiteSpeed reliably improves is how the site behaves under concurrent load, and how quickly cached pages are delivered. If your site is slow for other reasons, we’ll tell you what those are rather than pretend the server fixed them.
What is HTTP/3 and do I need it?+
It’s the newest version of the protocol browsers use to fetch web pages, designed to cope better with unreliable connections. You don’t need to do anything to use it, modern browsers negotiate it automatically when the server supports it. The benefit shows up mostly on mobile connections.
Why don’t more hosts use LiteSpeed?+
Mainly cost and inertia. Apache is free and it’s what most hosting infrastructure was built around years ago. LiteSpeed is commercially licensed, which is a real expense per server, one that’s easy for a large host to decline when the customer never sees which server their site is on.
