LiteSpeed Web Server: Why It Makes WordPress Sites Faster
Is LiteSpeed hosting faster than Apache for WordPress?
Usually, yes. LiteSpeed handles many connections efficiently and, together with the free LiteSpeed Cache plugin, can serve cached WordPress pages straight from the server without running PHP for every visit. On our own site, enabling it cut median page response times from roughly 650 to 970 ms to about 60 to 130 ms.
When you compare hosting plans, you will often see LiteSpeed listed as a feature. It sounds technical, and many buyers skip over it. In practice, the web server is one of the biggest factors in how fast a WordPress site feels, often more than the storage type or the amount of disk space.
This guide explains what LiteSpeed is and why it matters, using real measurements from spiderits.com. For the storage side of the speed question, see NVMe vs SSD hosting.

1. What a Web Server Does
The web server is the software that receives each visitor’s request and sends back the page. For WordPress, it passes the request to PHP, which builds the page from the database. Apache and Nginx are the most common web servers. LiteSpeed is a commercial alternative built for high performance and designed to work with existing Apache settings, so most sites can move to it without changes.
2. Why LiteSpeed Is Fast
- Event-driven design: it handles thousands of connections with little memory, so busy periods do not slow everything down.
- Server-level page cache: finished pages are stored by the server itself and delivered without running PHP or touching the database.
- Modern protocols: HTTP/3 and Brotli compression help pages load faster on mobile connections.
- Apache compatible: it reads .htaccess rules, so existing WordPress setups keep working.
3. Real Numbers From Our Own Site
spiderits.com runs on a LiteSpeed server with HTTP/3 and Brotli. When we installed and configured the LiteSpeed Cache plugin, we measured median page response times from Dhaka as an anonymous visitor before and after:
| Page | Before caching | After LiteSpeed Cache |
|---|---|---|
| Home | 973 ms | 103 to 133 ms |
| Business Websites | 963 ms | 85 to 91 ms |
| Pricing | 656 ms | 64 to 97 ms |
| Contact | 831 ms | 60 to 80 ms |
The server and hosting stayed the same. The difference came from letting LiteSpeed serve cached pages instead of rebuilding each one with PHP.
4. Setting Up LiteSpeed Cache Safely
- Install the free LiteSpeed Cache plugin from WordPress.org.
- Start with the default page cache settings and test your site.
- Exclude cart, checkout and account pages if you run WooCommerce (the plugin does this automatically for standard WooCommerce pages).
- Turn on CSS and JavaScript optimisation one option at a time, testing after each change, because these settings can break sliders and animations.
- Purge the cache after major design changes.
The official LiteSpeed Cache documentation explains each setting in detail.
5. LiteSpeed vs Apache vs Nginx at a Glance
| Web server | Strength | WordPress page cache |
|---|---|---|
| Apache | Very compatible, widely used | Needs a caching plugin running in PHP |
| Nginx | Fast and efficient | Server-level caching needs manual setup |
| LiteSpeed | Fast and Apache compatible | Built-in, managed from a free WordPress plugin |
Frequently Asked Questions
Is LiteSpeed Cache free?
Yes. The plugin is free, but its server-level page cache only works when the hosting runs LiteSpeed or OpenLiteSpeed.
Does LiteSpeed help WooCommerce stores?
Yes. Product and category pages can be cached for visitors, while carts and checkouts stay dynamic. Stores often see faster browsing and lower server load.
Can LiteSpeed Cache break my website?
Page caching is safe. The optional CSS and JavaScript minify and combine settings can cause layout problems, so enable them one at a time and test.
How do I know if my host uses LiteSpeed?
Check the plan details or ask support. You can also look for a server header that says LiteSpeed in your browser’s developer tools.
