LiteSpeed vs Nginx vs Apache: The Definitive WordPress Benchmark

Why Your Web Server Matters More Than You Think

When most people think about WordPress performance, they focus on plugins, caching, and CDNs. But there's a more fundamental layer that determines your baseline speed: the web server itself.

Your web server is the software that receives HTTP requests and serves your WordPress pages. The three main contenders are Apache, Nginx, and LiteSpeed. Let's see how they actually perform.

Our Testing Methodology

We ran identical WordPress installations across all three web servers with the following configuration:

WordPress 6.5 with WooCommerce (50 products)
PHP 8.2 with OPcache enabled
MySQL 8.0 database
4 vCPU / 8GB RAM server
Same theme (Astra) and plugins
Load testing tool: wrk with 100 concurrent connections

All tests were run 5 times, and we used the median result.

The Results

Requests Per Second

Apache:     1,204 req/s
Nginx:      2,450 req/s
LiteSpeed:  8,900 req/s

LiteSpeed handles 7.4x more requests than Apache and 3.6x more than Nginx under the same conditions.

Time to First Byte (TTFB)

Apache: 320ms average
Nginx: 180ms average
LiteSpeed: 85ms average

Memory Usage Under Load

Apache: 2.1GB (with mod_php)
Nginx: 890MB (with PHP-FPM)
LiteSpeed: 650MB (built-in LSPHP)

LiteSpeed uses 69% less memory than Apache while handling significantly more traffic.

Why LiteSpeed Wins

1. Event-Driven Architecture

Unlike Apache's process-based model, LiteSpeed uses an event-driven architecture similar to Nginx — but with a crucial advantage: native PHP processing.

While Nginx needs to proxy PHP requests to PHP-FPM (adding latency), LiteSpeed processes PHP natively through LSPHP, eliminating the middleman.

2. Built-in Cache Engine

LiteSpeed comes with LSCache, a built-in page caching solution that works at the server level — not the application level. This means:

Cache hits are served directly from memory
No PHP execution needed for cached pages
Automatic cache invalidation when content changes

3. Apache Compatibility

LiteSpeed reads .htaccess files natively, making migration from Apache seamless. You don't need to rewrite any of your existing configuration.

4. HTTP/3 & QUIC Support

LiteSpeed has native HTTP/3 support with QUIC protocol, providing faster initial connections — especially important for mobile users on unstable networks.

Real-World Impact

These benchmarks translate directly to real-world benefits:

Google Core Web Vitals: Better TTFB directly improves your LCP score
User Experience: Sub-100ms TTFB means pages feel instant
Traffic Handling: Handle traffic spikes without scaling infrastructure
SEO Rankings: Google uses page speed as a ranking factor

How GetHost.One Uses LiteSpeed

Every GetHost.One server runs LiteSpeed Enterprise (not the open-source version) with:

Pre-configured LSCache for WordPress
Redis Object Cache for database query caching
HTTP/3 enabled by default
Optimized PHP workers for your traffic patterns

The result? An average TTFB of 85ms across all customer sites — out of the box, with zero configuration required.

Make the Switch

If you're still running on Apache or even Nginx, you're leaving performance on the table. LiteSpeed Enterprise is the fastest web server for WordPress — and it's included in every GetHost.One plan.
