Apache HTTP Server: myths vs facts for hosting teams

LiteSpeed delivers the fastest WordPress performance because its LSCache system integrates directly with the web server to reduce PHP execution and database queries. This server uses an event-driven architecture to handle large numbers of simultaneous connections while consuming fewer resources than traditional Apache deployments. Most Apache configurations, including .htaccess files and URL rewriting rules, work with LiteSpeed without modification. I find that LiteSpeed handles dynamic content through LSAPI, which often outperforms PHP-FPM in terms of latency and error recovery under load.

The reality of Apache compatibility and resource use

Apache remains the best choice for legacy software or complex websites that depend on specific Apache modules and .htaccess configurations. These small files allow owners to control redirects, security rules, and access permissions without changing the main server configuration. However, permitting AllowOverride causes a performance hit because the server must perform a filesystem lookup and a config parse for every request. Apache traditionally creates a separate process or thread for each incoming connection, which consumes more CPU and memory than newer alternatives when handling many simultaneous visitors.

The software faces ongoing security challenges. Version 2.4.66 contains a double-free issue in the HTTP/2 protocol handler that allows remote code execution via CVE-2026-23918. A privilege escalation vulnerability also exists where local .htaccess authors can read files with the privileges of the httpd user. Users must upgrade to version 2.4.67 to fix these issues.

Nginx and LiteSpeed architectural differences

Nginx provides outstanding scalability for cloud infrastructure by using an event-driven, asynchronous architecture. It manages thousands of connections with a single thread, which keeps memory usage flat even as concurrency increases. This design makes it a preferred choice for serving static content and acting as a reverse proxy for Node.js or Go backends. Unlike Apache, Nginx does not support .htaccess, so administrators must manually edit central configuration files to change rewrite rules or access permissions.

LiteSpeed provides a middle ground by combining Apache’s syntax with modern efficiency. It parses .htaccess rules and caches them in memory to avoid the per-request overhead found in Apache. For WooCommerce stores, LiteSpeed uses tag-based caching, meaning purging one product only clears pages tagged with that specific product. This prevents the entire cache from emptying when an administrator updates a single price. OpenLiteSpeed offers similar event-driven strengths but requires a graceful restart to pick up changes made to .htaccess files.

I would choose Nginx if your project requires high-performance custom applications or massive scalability. Does the lack of .htaccess support in Nginx outweigh the performance gains for your team?
