LiteSpeed vs Apache vs Nginx: How Your Server Software Affects Speed

Every web page you visit is served by one of three pieces of software: Apache, Nginx, or LiteSpeed. Most hosting providers never tell you which one runs on their servers. That matters, because the web server software affects how fast your site loads, how many concurrent visitors it can handle, and which caching technologies are available to you.

This is not an abstract benchmark comparison. We looked at what real hosting providers actually run, what their plans cost, and what it means for your site's performance.

The Three Web Servers, Explained Simply

Apache (The Original)

Apache HTTP Server has been around since 1995. It powers roughly 30% of all websites as of 2026, down from over 60% a decade ago. Apache uses a process-based (or thread-based) model: each incoming connection gets its own process or thread. This works fine for low-to-moderate traffic, but under heavy load, Apache consumes more RAM because each connection reserves resources even while waiting for data.

The .htaccess file is Apache's signature feature. It lets you add per-directory configuration without touching the main server config. This is why shared hosting loves Apache. Every customer can have their own rewrite rules, redirects, and access controls without needing root access. WordPress, Joomla, and most PHP CMSes ship with .htaccess files by default.

The downside: .htaccess adds overhead. Apache checks for these files on every request, walking up the directory tree. On a shared server with hundreds of accounts, that extra I/O adds up.

Nginx (The Performance King)

Nginx (pronounced "engine-x") was created in 2004 specifically to solve Apache's performance limitations. Instead of spawning a process per connection, Nginx uses an event-driven, asynchronous architecture. A single Nginx worker process can handle thousands of simultaneous connections using minimal RAM.

This makes Nginx dramatically better at serving static files (images, CSS, JavaScript) and handling many concurrent users. It is the default reverse proxy for most modern web applications, including Node.js, Python, Ruby, and Go apps. Nginx serves static content directly and forwards dynamic requests to the application backend.

The trade-off: Nginx does not support .htaccess files. All configuration happens in the main server config, which typically requires root access. On managed platforms like Kinsta and Cloudways, this is handled for you. On shared hosting, the lack of .htaccess support is why you rarely see Nginx as the primary web server.

LiteSpeed (The Modern Hybrid)

LiteSpeed Web Server combines Apache's compatibility with Nginx's performance model. It reads Apache configuration files and .htaccess rules natively, so it works as a drop-in Apache replacement. But internally, it uses an event-driven architecture similar to Nginx, handling thousands of connections per worker process.

LiteSpeed's biggest advantage for shared hosting: the LiteSpeed Cache (LSCache) plugin. This server-level cache stores pre-rendered pages in shared memory, bypassing PHP entirely for cached requests. The WordPress LiteSpeed Cache plugin has over 5 million active installations and is one of the most effective caching solutions available for the platform.

LiteSpeed comes in two editions. OpenLiteSpeed is free and open source. LiteSpeed Enterprise is commercial and includes features like QUIC/HTTP/3 support, per-account resource isolation, and better Apache compatibility. Most shared hosting providers run the Enterprise edition.

Performance Differences: What Actually Matters

Static File Serving

Nginx and LiteSpeed are both significantly faster than Apache at serving static files. In benchmark scenarios with 10,000+ concurrent connections, Apache's response time increases sharply as each connection consumes a thread. Nginx and LiteSpeed maintain flat response times because their event-driven architectures do not tie resources to individual connections.

For a typical WordPress site, static files (images, CSS, JS) make up 80-90% of all requests. This is where the server software choice has the most visible impact on page load speed.

PHP Processing

All three servers process PHP through a separate handler (PHP-FPM or equivalent). The web server receives the request, passes it to PHP, and returns the result. LiteSpeed has its own built-in PHP handler (LSPHP) that avoids the overhead of the FastCGI protocol, giving it a slight edge for PHP-heavy sites.

Apache with mod_php embeds PHP directly into the web server process. This is fast but means every Apache process carries the PHP interpreter's memory footprint, even for static file requests. Apache with PHP-FPM separates the two, improving memory efficiency at the cost of a small communication overhead.

Caching

This is where LiteSpeed pulls ahead of both competitors for shared hosting use cases. LiteSpeed Cache operates at the server level, storing full page caches in shared memory. Nginx can do similar things with FastCGI Cache or proxy cache, but configuring it requires root access and server config edits. Apache relies entirely on application-level caching (like WP Super Cache or W3 Total Cache), which is slower because it still invokes PHP to serve cached pages.

Which Hosting Providers Use Which Server?

Here is what the providers in our database actually run.

Provider	Web Server	LiteSpeed Cache	Starting Price	Entry Plan Storage
A2 Hosting	LiteSpeed	Yes	$3.99/mo	15 GB NVMe SSD
Hostinger	LiteSpeed	Yes	$1.99/mo	20 GB SSD
GreenGeeks	LiteSpeed	Yes	$2.95/mo	25 GB SSD
FastComet	LiteSpeed	Extra plan only	$1.79/mo	10 GB
HostArmada	Nginx	No	$1.99/mo	15 GB NVMe
SiteGround	Nginx (custom)	No (SuperCacher)	$2.99/mo	10 GB SSD
Kinsta	Nginx	No (Edge Caching)	$29.17/mo	10 GB
Cloudways	Apache + Nginx	No (Varnish)	$14/mo	25 GB

A clear pattern emerges. Budget shared hosting providers ($1.99-$3.99/mo range) tend to use LiteSpeed because it gives the best performance per dollar on shared servers. Premium managed providers like Kinsta and Cloudways use Nginx because they control the full server stack and can configure caching at the infrastructure level.

LiteSpeed Providers: Closer Look

A2 Hosting

A2 Hosting runs LiteSpeed on all shared plans. Their Starter plan at $3.99/month gives you 15 GB NVMe SSD, 2 vCPU, and 2 GB RAM. The Turbo plans use LiteSpeed Enterprise with built-in caching that A2 claims makes sites load up to 20x faster than basic Apache hosting. Their Pro plan ($6.99/mo) upgrades to 50 GB NVMe, 4 vCPU, and 6 GB RAM.

Hostinger

Hostinger uses LiteSpeed with the QUIC.cloud CDN integration. Their Business plan at $2.99/month includes 50 GB NVMe storage, 2 CPU cores, and 3 GB RAM. The LiteSpeed Cache plugin comes pre-installed on WordPress plans. For the price point, this is hard to beat for PHP/WordPress performance.

GreenGeeks

GreenGeeks runs LiteSpeed on all shared hosting plans. Their Lite plan starts at $2.95/month with 25 GB SSD storage and unmetered bandwidth. They also include a free CDN. The Pro plan ($4.95/mo) doubles storage to 50 GB and adds better caching and on-demand backups.

Nginx Providers: Closer Look

SiteGround

SiteGround uses a custom Nginx setup with their proprietary SuperCacher technology. SuperCacher has three levels: static cache, dynamic cache (full page caching), and Memcached for object caching. The StartUp plan begins at $2.99/month with 10 GB SSD storage. GrowBig at $4.99/month adds 50 GB and the full SuperCacher suite. GoGeek at $7.99/month provides 100 GB and priority support.

SiteGround's renewal prices are steep. StartUp jumps to $17.99/month, GrowBig to $29.99/month, and GoGeek to $44.99/month after the initial term. Factor this into your decision using the True Cost Calculator.

Kinsta

Kinsta runs Nginx on Google Cloud Platform with a custom caching layer and Cloudflare CDN integration. Their entry plan starts at $29.17/month (yearly billing) and includes 35,000 visits, 10 GB storage, and server-level caching plus Edge Caching through Cloudflare. This is premium pricing, but Kinsta's Nginx stack is heavily optimized for WordPress performance.

Does the Web Server Matter More Than the Plan Specs?

Honestly, for most websites? The caching layer matters more than the web server itself. A WordPress site on Apache with a properly configured WP Super Cache will outperform a misconfigured LiteSpeed site every time. The server software sets the performance ceiling. Caching determines how close you get to it.

That said, LiteSpeed's integrated cache is easier to set up correctly than Nginx FastCGI Cache (which needs root access) or Apache with a WordPress caching plugin (which requires trial and error). For shared hosting customers who just want things to be fast without tinkering, LiteSpeed with the LSCache plugin is the path of least resistance.

Recommendations by Use Case

WordPress on Shared Hosting

Go with a LiteSpeed provider. Hostinger at $2.99/month (Business plan) or A2 Hosting at $3.99/month gives you LiteSpeed + LSCache out of the box. Install the LiteSpeed Cache plugin, enable page caching and image optimization, and your WordPress site will load faster than most sites on higher-priced plans.

High-Traffic WordPress

Kinsta (Nginx + Cloudflare CDN) or Cloudways (Nginx reverse proxy + Varnish) handle traffic spikes better than shared hosting regardless of web server. The managed infrastructure, automatic scaling, and CDN integration matter more at this level than the difference between Nginx and LiteSpeed.

Custom Web Applications (Node.js, Python, Go)

Nginx is the standard. Use it as a reverse proxy in front of your application server. DigitalOcean or Vultr VPS plans starting at $5-6/month give you full control over the Nginx configuration. LiteSpeed's advantages are PHP-specific and do not apply to non-PHP applications.

E-commerce (WooCommerce)

LiteSpeed with the LSCache WooCommerce integration handles product pages, cart caching, and checkout exclusions well. A2 Hosting's Pro plan ($6.99/mo with 4 vCPU and 6 GB RAM) or Hostinger's Cloud Startup ($6.99/mo with 4 CPU and 4 GB RAM) are solid choices. For larger stores, a managed solution like Cloudways with Varnish caching provides better scalability.

The Bottom Line

Apache is the legacy option. It works, it is everywhere, and .htaccess makes shared hosting possible. But it is the slowest of the three under load.

Nginx is the performance standard for managed and custom hosting. If you control your server, Nginx is almost always the right choice. It serves static files faster, uses less memory, and scales better under concurrent traffic.

LiteSpeed is the best option for shared hosting customers running PHP/WordPress. The built-in caching, .htaccess compatibility, and event-driven architecture give you Nginx-level performance without needing root access or custom server configuration. Providers like Hostinger, A2 Hosting, and GreenGeeks all run LiteSpeed on their shared plans, with prices starting under $3/month.
